Tissot Seastar Powermatic 80 40mm Turquoise Dial
The Tissot Seastar Powermatic 80 40mm Turquoise Dial combines Swiss automatic watchmaking, serious aquatic capability and a striking contemporary colour treatment in a versatile 40 mm format. Its graded turquoise-to-black dial gives the watch a distinctive visual identity, while the robust stainless-steel construction and Powermatic 80 movement provide the technical substance expected from the Seastar 1000 collection.
Reference T120.807.11.091.00 features a 40 mm 316L stainless-steel case that offers a more compact alternative to larger professional-inspired diving watches. The balanced proportions provide enough wrist presence to retain the unmistakable Seastar character while remaining highly practical for everyday wear.
The dial is one of the defining features of the Tissot Seastar Powermatic 80 40mm Turquoise Dial. Its turquoise centre gradually transitions towards darker tones around the perimeter, creating a dramatic gradient effect that changes subtly under different lighting conditions.
Tissot protects the dial with scratch-resistant sapphire crystal, while Super-LumiNova® improves visibility when ambient light is reduced.
At the heart of the watch is Tissot’s Swiss automatic Powermatic 80 movement, delivering up to 80 hours of power reserve. This extended autonomy allows the watch to continue operating for more than three days when fully wound.
Combined with a screw-down crown and caseback, rotating bezel and 300 m / 1000 ft water resistance, the Tissot Seastar Powermatic 80 40mm Turquoise Dial combines mechanical sophistication with genuine sports-watch capability.

Balanced 40mm Seastar Design
The Tissot Seastar Powermatic 80 40mm Turquoise Dial offers a particularly versatile interpretation of Tissot’s automatic diving-watch design.
Its 40 mm stainless-steel case provides a strong sporting presence while remaining noticeably easier to wear than larger 43 mm or 45 mm diving watches.
This makes the model especially appealing to wearers who appreciate the technical character of the Seastar collection but prefer more restrained proportions.
The stainless-steel architecture provides strength and corrosion resistance, while the carefully finished surfaces maintain the premium appearance expected from a Swiss Made Tissot.
The result is a watch capable of moving naturally between active environments and everyday situations.
Graded Turquoise-Black Dial
The most distinctive visual feature of the Tissot Seastar Powermatic 80 40mm Turquoise Dial is its graded turquoise-to-black dial.
The vibrant turquoise centre creates an immediate point of interest, while the darker outer areas add depth and reinforce the diving-inspired personality of the watch.
This gradient treatment gives the dial a more dynamic appearance than a conventional flat colour.
As surrounding light changes, the turquoise tones can appear brighter or deeper, creating a watch that feels visually different throughout the day.
Clear indexes and luminous hands preserve the functional legibility expected from the Seastar collection.
Super-LumiNova® further improves visibility in reduced-light conditions, while the date display adds practical everyday functionality.
Powermatic 80 Automatic Movement
Inside the Tissot Seastar Powermatic 80 40mm Turquoise Dial is Tissot’s Swiss automatic Powermatic 80 movement.
The movement is mechanically powered through wrist motion and does not require the conventional battery used by quartz watches.
Its major practical advantage is the power reserve of up to 80 hours.
When fully wound, the Tissot Seastar Powermatic 80 40mm Turquoise Dial can continue operating for more than three days without being worn.
This extended reserve makes the watch especially convenient for someone who rotates between several timepieces or removes the watch during a weekend.
The automatic architecture also provides the traditional mechanical character valued by watch enthusiasts.

Nivachron™ Balance Spring
The Powermatic 80 movement incorporates Tissot’s patented Nivachron™ balance spring.
Mechanical watches can be influenced by magnetic fields created by smartphones, computers and other electronic devices encountered in everyday environments.
Nivachron™ technology is designed to improve resistance to these magnetic influences.
For the Tissot Seastar Powermatic 80 40mm Turquoise Dial, this adds another layer of modern engineering to the traditional mechanical movement.
Together with the 80-hour power reserve, Nivachron™ helps make the watch particularly practical for regular everyday ownership.
Rotating Diving Bezel
The Tissot Seastar Powermatic 80 40mm Turquoise Dial incorporates an anti-clockwise rotating bezel inspired by traditional diving-watch functionality.
The unidirectional configuration follows the established safety principle used for monitoring elapsed underwater intervals.
Outside diving environments, the bezel can also be useful for timing everyday activities.
Visually, the dark bezel frames the turquoise gradient dial and strengthens the black-and-turquoise colour combination that gives this particular reference its distinctive character.
The result is both a functional component and an important part of the overall design.
Sapphire Crystal
Protecting the dial of the Tissot Seastar Powermatic 80 40mm Turquoise Dial is scratch-resistant sapphire crystal.
Sapphire provides excellent resistance against everyday surface scratching, making it particularly suitable for a sports watch intended for frequent wear.
Tissot also incorporates antireflective treatment to improve clarity and reduce distracting reflections under changing lighting conditions.
This is especially useful with the gradient dial, allowing its turquoise tones and luminous details to remain clearly visible.
Combined with the stainless-steel case and robust bezel construction, sapphire contributes significantly to the long-term durability of the watch.
See-Through Caseback
The Tissot Seastar Powermatic 80 40mm Turquoise Dial features a see-through caseback that allows the automatic movement to remain visible.
This creates an attractive contrast between the rugged sports-watch exterior and the mechanical engineering inside.
For someone purchasing a first automatic watch, the transparent caseback provides a direct view of the movement at work.
For experienced enthusiasts, it adds another element of interest to a watch already distinguished by its technical specifications and unusual dial treatment.
Stainless-Steel Bracelet
The stainless-steel bracelet reinforces the robust character of the Tissot Seastar Powermatic 80 40mm Turquoise Dial.
Its construction complements the stainless-steel case and provides the solid wrist feel expected from a Swiss sports watch.
The bracelet incorporates a secure folding clasp designed for active everyday use.
Tissot also uses an interchangeable quick-release system on the Seastar platform, making compatible strap changes more convenient.
This provides additional flexibility for owners who want to adapt the watch to different occasions or seasons.
300m Water Resistance
One of the defining specifications of the Tissot Seastar Powermatic 80 40mm Turquoise Dial is its impressive 30 bar / 300 metres / 1000 feet water resistance.
A screw-down crown and caseback help support the water-resistant architecture, while the rotating bezel provides the elapsed-time functionality traditionally associated with aquatic sports watches.
The 1000 designation in the Seastar name refers to approximately 1,000 feet of water resistance, equivalent to around 300 metres.
These capabilities give the Seastar genuine technical credibility rather than merely a diving-inspired appearance.
Mechanical Performance Meets Everyday Versatility
The Tissot Seastar Powermatic 80 40mm Turquoise Dial successfully combines traditional mechanical watchmaking with modern sports-watch practicality.
The Powermatic 80 movement provides extended autonomy, while Nivachron™ introduces improved resistance to magnetic influences.
At the same time, sapphire crystal, screw-down construction and 300 m water resistance provide the durability expected from the Seastar family.
What makes this particular reference especially appealing is that all of this capability is packaged inside a versatile 40 mm case.
The result is an automatic sports watch that can deliver substantial technical performance without feeling unnecessarily oversized.
A Distinctive Swiss Automatic Sports Watch
The Tissot Seastar Powermatic 80 40mm Turquoise Dial brings together one of the most distinctive dial treatments in the Seastar collection with practical dimensions and proven Swiss mechanical engineering.
Its graded turquoise-to-black dial creates immediate visual impact, while the 40 mm stainless-steel case keeps the watch balanced and wearable.
The Powermatic 80 movement provides up to 80 hours of autonomy, while Nivachron™, sapphire crystal and 300 m water resistance reinforce its technical credentials.
For someone searching for a Swiss automatic sports watch with distinctive colour, serious aquatic capability and exceptional everyday versatility, the Tissot Seastar Powermatic 80 40mm Turquoise Dial is an excellent choice.

The dial features a distinctive turquoise gradient treatment that darkens toward black at the perimeter.
This gives the watch its dramatic graded turquoise-black appearance while creating greater visual depth than a conventional flat dial.
Does the Tissot Seastar have sapphire crystal?
Yes. The dial is protected by scratch-resistant sapphire crystal with antireflective treatment.
Sapphire provides excellent resistance against everyday surface scratches and contributes significantly to long-term durability.

This allows the wearer to view the mechanical automatic movement and adds another level of interest for anyone who appreciates mechanical watchmaking.
Does the watch need a battery?
No. The Powermatic 80 is a mechanical automatic movement and therefore does not rely on a conventional quartz battery.
Does the watch require winding?
Normal wrist movement automatically winds the movement.
If the watch has stopped after being left unworn for an extended period, it can be manually restarted according to Tissot’s official instructions.
Is the Tissot Seastar water resistant?
Yes. The Tissot Seastar Powermatic 80 40mm Turquoise Dial is water resistant to 30 bar / 300 metres / 1000 feet.
This substantial rating is one of the defining technical characteristics of the Seastar 1000 family.

The 1000 designation refers to approximately 1,000 feet of water resistance, equivalent to around 300 metres.
Does the Tissot Seastar have a screw-down crown?

The crown should always be properly secured before exposure to water.

Does the bezel rotate?
Yes. The Tissot Seastar Powermatic 80 40mm Turquoise Dial features an anti-clockwise rotating bezel.
The unidirectional configuration follows the traditional safety principle associated with diving watches.
Is the Tissot Seastar suitable for swimming?
Its 300 m water resistance and screw-down construction make the watch highly capable around water.
Always ensure that the crown is fully secured before entering the water.
Is it suitable for diving?
The model combines 300 m water resistance, screw-down architecture and a unidirectional rotating bezel, giving it the fundamental technical characteristics associated with a capable diving-oriented sports watch.

It maintains the strong visual identity of a diving watch while remaining compact enough for regular use and a broad range of wrist sizes.
Is the turquoise dial easy to style?
Despite its distinctive colour, yes.
The black gradient around the outer dial, stainless-steel case and neutral bracelet help balance the brighter turquoise centre.
This makes the Tissot Seastar Powermatic 80 40mm Turquoise Dial more versatile than a completely bright turquoise sports watch.
Is the Powermatic 80 suitable for everyday use?
Yes. The extended 80-hour power reserve makes it especially practical for daily ownership.
The watch can be removed for several days and may still be operating when worn again.
Is Powermatic 80 better than quartz?
The two movements serve different priorities.
Quartz generally offers greater absolute accuracy and lower maintenance, while the Powermatic 80 provides the character and engineering appeal of traditional mechanical watchmaking.
The Tissot Seastar Powermatic 80 40mm Turquoise Dial is particularly suitable for someone who values an automatic movement and visible mechanical engineering.
Is the Tissot Seastar Powermatic 80 40mm Turquoise Dial a good gift?
Yes. Its unusual turquoise gradient dial, Swiss automatic movement, 80-hour reserve and 300 m water resistance make the Tissot Seastar Powermatic 80 40mm Turquoise Dial an exceptional gift for someone who appreciates distinctive mechanical watches.
