Tissot SeaStar 1000 Two Tone 40 mm 300M Quartz Watch

SeaStar 1000 Two Tone 40 mm diver

The SeaStar 1000 Two Tone is a 40.00 mm stainless-steel diver with a quartz movement and 300 m water resistance. A unidirectional rotating bezel and sapphire crystal protect the black dial with dotted markers and a date display. The two-tone bracelet matches the case material. It suits wearers who want a certified diver aesthetic with battery-powered convenience.

Before ordering verify wrist fit and crown operation

Confirm the 40.00 mm case diameter and 9.97 mm thickness suit your wrist proportions. Check that the screw-down crown and unidirectional bezel turn smoothly before exposing the watch to pressure. Ensure the stainless-steel bracelet can be sized by a watchmaker if the supplied links are too long or short. Buyers who need a larger case diameter or a mechanical movement should consider other models.

Sustained pressure and daily wear

The 300 m rating is tested for static pressure at depth, not only brief splashes. Quartz regulation keeps timekeeping stable during long immersions without winding. Sapphire crystal resists scratches from sand and equipment contact over months of use. The stainless-steel case and bracelet tolerate saltwater exposure when rinsed after each dive.
