Tissot Seastar 1000 40 mm Automatic Diver

The Tissot Seastar 1000 is a stainless steel automatic diver watch with a 40.00 mm case and a grey and black dial. It offers 300m water resistance, a sapphire crystal and a unidirectional rotating bezel. The see-through case back reveals the automatic movement. A deployment clasp secures the stainless steel bracelet.

Who this suits and who should look elsewhere

This watch suits wearers who want a 40 mm automatic diver with 300m water resistance and a steel bracelet. Buyers who need a thinner case profile should look elsewhere. Buyers who prefer a rubber or fabric strap should look elsewhere. Buyers who want a quartz movement should look elsewhere.

Deciding specification: 300m water resistance

The 300m water resistance rating is the single specification that decides whether this is the right part. It covers recreational diving and serious surface water sports. Without that rating the watch would not meet the needs of a diver's watch buyer.

Questions about this item

How much heat or noise does the automatic movement generate when worn all day?

The automatic movement runs from wrist motion alone, producing no audible noise and no noticeable heat during continuous wear.

What must I already own for this watch to function?

No external power source or accessory is needed; the movement winds itself through natural arm motion while on the wrist.

Will the 40 mm stainless steel case and 20 mm lug spacing fit the NATO straps I already use?

The 40 mm case uses standard lug width, so existing NATO or rubber straps with matching spring bars will attach directly.
