Design and construction
The 45.5mm round case gives this Seastar 1000 Chronograph a deliberately commanding profile, reinforced by its 180g weight and 12.8mm thickness. Silver-toned 316L stainless steel, a blue dial and a stainless steel bracelet create a classic sporty appearance.
The scratch-resistant sapphire crystal is paired with double-sided anti-reflective coating, while the folding clasp includes both a safety mechanism and diver extension. That combination supports secure everyday wear and makes room for use over suitable exposure clothing.
Timing and everyday operation
The ETA G10.212 quartz movement keeps the feature set practical, with a chronograph offering 30-minute, 1/10-second and 60-second indications. ADD and SPLIT functions extend its usefulness beyond simple elapsed-time measurement, while the date display adds everyday convenience.
The EOL battery indicator provides advance notice that battery replacement is due. Luminous hands and markers should help with reading the dial in low light, and the blue dial is protected by the rotating bezel arrangement associated with dive-watch designs.
Water resistance and suitability
With 300m or 30 ATM water resistance, this is built for substantially more than occasional splash protection. The unidirectional rotating bezel, diver extension and luminous display all support its stated tool-watch character.
Its generous dimensions are central to the wearing experience. Buyers should be comfortable with a large, weighty watch before choosing it, but those who are will receive a highly specified chronograph with strong aquatic credentials and a durable bracelet-led build.
