Tissot Seastar 40mm Blue Dial
The Tissot Seastar 40mm Blue Dial combines Swiss precision, serious aquatic capability and versatile contemporary styling in a balanced 40 mm format. Designed for those who appreciate the character of a diving-inspired sports watch without oversized proportions, this Seastar 1000 delivers impressive technical performance together with everyday wearability.
Its 40 mm 316L stainless-steel case provides confident wrist presence while remaining compact enough for regular use. The case measures only 9.97 mm thick, helping the watch maintain a relatively streamlined profile despite its substantial water-resistance specification.
The blue dial gives the Tissot Seastar 40mm Blue Dial its unmistakable maritime identity. The rich colour pairs naturally with the stainless-steel case and bracelet, creating a classic sports-watch combination that remains easy to wear throughout the year.
Tissot protects the dial with scratch-resistant sapphire crystal featuring double-sided antireflective coating, while Super-LumiNova® on the hands improves visibility in reduced-light conditions.
Inside, a Swiss Quartz three-hand movement provides dependable accuracy and uncomplicated everyday ownership. The movement includes a practical date function and EOL battery end-of-life indicator.
With 300 m / 1000 ft water resistance, a screw-down crown and caseback and an anti-clockwise rotating bezel, the Tissot Seastar 40mm Blue Dial offers genuine aquatic capability beneath its refined exterior.

Balanced 40mm Seastar Design
The Tissot Seastar 40mm Blue Dial offers one of the most versatile case sizes within Tissot’s modern sports-watch range.
At 40 mm in diameter, the watch provides enough presence to preserve the strong visual identity associated with a diving watch while remaining noticeably easier to wear than larger 43–46 mm sports models.
Its 9.97 mm thickness also contributes to comfortable everyday proportions.
This balance allows the Tissot Seastar 40mm Blue Dial to transition naturally between active environments, casual clothing and smart-casual situations.
The 316L stainless-steel case provides durability and corrosion resistance, while the carefully finished metallic surfaces give the watch a refined Swiss Made appearance.
Classic Blue Dial
The blue dial is the defining visual characteristic of the Tissot Seastar 40mm Blue Dial.
Blue has long been associated with aquatic watches, making it a natural choice for the Seastar family.
The colour delivers more personality than traditional black while remaining considerably more versatile than brighter sports-watch tones.
Tissot combines the blue surface with index hour markers and clear hands to maintain excellent legibility.
Super-LumiNova® on the hands improves visibility when surrounding light decreases.
A practical date display adds everyday functionality without disturbing the clean three-hand layout.
The result is a dial that feels sporty and contemporary while retaining the timeless appeal expected from a Swiss watch.
Swiss Quartz Precision
Inside the Tissot Seastar 40mm Blue Dial is a Swiss Quartz three-hand movement engineered for accuracy, reliability and straightforward everyday use.
The movement uses a Renata 371 battery at 1.55 V and includes an EOL battery end-of-life indicator.
EOL functionality provides advance warning when battery replacement is approaching, adding another practical advantage to the quartz architecture.
Unlike an automatic mechanical movement, quartz does not require regular wrist movement to maintain a power reserve.
The Tissot Seastar 40mm Blue Dial can therefore be left unworn and remain ready whenever it is needed.
For someone who values precision and minimal maintenance, this makes the Seastar especially convenient.

Anti-Clockwise Rotating Bezel
The Tissot Seastar 40mm Blue Dial incorporates an anti-clockwise rotating bezel, a defining functional element of traditional diving-watch design.
The unidirectional construction is designed so that accidental movement cannot incorrectly extend a measured underwater interval.
Tissot describes the Seastar 1000 series as using its rotating bezel for reliable underwater timing.
Even outside diving environments, the bezel can be useful for timing short everyday intervals.
Visually, it frames the blue dial and reinforces the performance-oriented character of the watch.
Sapphire Crystal with Double AR Coating
Protecting the blue dial is scratch-resistant sapphire crystal with double-sided antireflective coating.
Sapphire provides excellent resistance against everyday surface scratches, making it particularly appropriate for an active sports watch.
The antireflective treatment helps reduce distracting reflections from both sides of the crystal.
This improves clarity and allows the rich blue dial of the Tissot Seastar 40mm Blue Dial to remain easily visible under changing lighting conditions.
Combined with the robust stainless-steel construction, the sapphire crystal contributes significantly to long-term durability.
Screw-Down Construction
The Tissot Seastar 40mm Blue Dial features both a screw-down crown and screw-down caseback.
These features form an important part of the watch’s substantial water-resistant architecture.
The screw-down crown helps maintain a secure seal around one of the primary entry points into the case, while the screw-down caseback supports structural integrity under pressure.
This engineering reinforces the fact that the Seastar is not simply styled to resemble a diving watch.
Its external construction has been designed around genuine aquatic capability.
Stainless-Steel Bracelet
The Tissot Seastar 40mm Blue Dial is fitted with a stainless-steel bracelet that complements the 40 mm case.
Tissot specifies bracelet reference T605048264, finished in grey stainless steel.
A folding clasp with safety lock and push-buttons provides secure everyday fastening.
The bracelet also incorporates Tissot’s interchangeable quick-release system, allowing compatible straps or bracelets to be changed more conveniently.
This gives the watch additional flexibility for owners who enjoy adapting its appearance to different seasons or occasions.
300m Water Resistance
One of the defining technical characteristics of the Tissot Seastar 40mm Blue Dial is its impressive 30 bar / 300 metres / 1000 feet water resistance.
This rating places it far beyond the level of an ordinary everyday watch.
The 1000 designation in the Seastar name refers to approximately 1,000 feet of water resistance, equivalent to around 300 metres.
Tissot combines this substantial rating with a screw-down crown and caseback and a unidirectional rotating bezel.
Together, these features give the watch genuine sporting credibility and make aquatic capability a central part of its design rather than a decorative theme.
Everyday Precision Meets Aquatic Capability
The Tissot Seastar 40mm Blue Dial successfully combines practical Swiss Quartz precision with the robust construction of a modern sports watch.
Its movement provides accurate, low-maintenance timekeeping.
At the same time, sapphire crystal, screw-down architecture, a rotating bezel and 300 m water resistance give the watch serious technical substance.
The 40 mm case keeps those capabilities accessible in a format that remains comfortable enough for everyday use.
Its blue-and-steel design also provides excellent versatility, allowing the Tissot Seastar 40mm Blue Dial to move easily from active environments to relaxed everyday situations.
A Versatile Swiss Sports Watch
The Tissot Seastar 40mm Blue Dial brings together the essential characteristics of a modern Swiss sports watch in a particularly balanced package.
Its 40 mm stainless-steel case provides confident presence without unnecessary bulk.
The classic blue dial creates an unmistakable maritime aesthetic, while Swiss Quartz precision delivers dependable everyday accuracy.
Sapphire crystal, Super-LumiNova®, screw-down construction and 300 m water resistance provide the technical foundation expected from the Seastar 1000 family.
