About this watch
The Tissot Seastar 1000 Chronograph T120.417.11.051.00 brings together a black dial, steel bracelet and a substantial 45.5 mm case. Its chronograph display gives it a different character from the simpler three-hand Seastar models.
A larger Seastar with stopwatch functions
The black dial and matching bezel keep the design cohesive, while the bracelet adds a solid steel finish. Choose this model when you want a prominent sports watch with elapsed-time measurement. Its size deserves attention: compare the case diameter with your current watch before ordering.
Is this an automatic Seastar?
No. This reference uses a Swiss quartz chronograph movement. The chronograph measures time intervals; it does not mean the watch is automatic.

Key features.
Tissot Seastar 1000 Chronograph - Black Dial T120.417.11.051.00
Built to stay clear.
The crystal is the transparent cover over the dial. This Seastar uses scratch-resistant sapphire to help protect the display through everyday wear, while keeping the hands and markers clearly visible.
Less reflection. More dial.
Anti-reflective coating helps reduce glare on the crystal, making the dial easier to read as the light changes.
45.5 mm case.
This reference has a 45.5 mm case. Compare that measurement with a watch you already enjoy wearing. Case diameter is only part of the fit: the bracelet or strap and the way the lugs sit also affect comfort.

Swiss precision.
Swiss quartz timekeeping runs on a battery, so daily winding is unnecessary. Set the time and date, then let the movement keep track while you get on with your day.
Precision, without the winding.
A battery supplies the energy. An electronic circuit uses the regular vibration of a quartz crystal to regulate the movement, while a small motor drives the hands. It is a practical choice for a watch you can pick up and wear.
- No daily winding
- Keeps running between wears
- Replaceable battery; professional servicing
Every counter has a purpose.
The chronograph measures elapsed time separately from the regular time display. Use the controls only when the watch is dry.
Easy to live with.
This is a battery-powered quartz watch. Battery life varies with use and conditions. Have a qualified watchmaker replace the battery and check the seals and water resistance.
Ask a question
Made for time by the water.
300 m / 30 bar
The rotating bezel lets you keep track of elapsed time at a glance. A screw-down crown and case back help seal the case.
Close the crown securely before water contact. Never adjust the crown or operate chronograph pushers underwater. Water resistance depends on the condition of the seals, so regular checks matter.
How to care for itA little care goes a long way.
Ask a questionKeep the finish clean
Use a soft cloth for everyday cleaning. Avoid solvents, perfume and harsh detergents, which can affect the case, strap or seals.
Keep water resistance checked
Tissot recommends an annual water-resistance check. Have the watch inspected after a hard impact and avoid sudden temperature changes.
