Automatic Diver Watch 40mm - Sapphire Glass, Steel - Corletaria

Some men wear a watch to check the hour - others wear a machine that quietly reflects how seriously they take every minute.

This automatic diver was curated for the second group. The men who move between flights, negotiations and late-night drives without asking if their watch can keep up. It is not costume. It is the one instrument that stays on your wrist when every screen is dark and the next decision is yours alone.

The ritual begins as you fasten the bracelet. You feel the weight of the stainless steel case and bracelet, hear the muted rotation of the Japanese automatic movement waking as it senses motion. On the commute, in the boardroom or at the bar, the 40mm diver profile sits with quiet authority. The sunburst dial and colored bezel catch light like open water, never shouting, always present.

This is a watch built to be used daily, not stored. The 40mm diameter and 12mm thickness sit securely on most wrists, sliding under a cuff yet looking right with a T-shirt and leather jacket. The 10 bar water resistance means rain, sinks and poolside afternoons are non-events. Luminous hands and markers stay legible when the meeting overruns or the drive home stretches into the night, while the magnified date window under sapphire crystal keeps schedules anchored.

At its core is the proven Seiko NH35 automatic caliber. No charging cables, no batteries, no software updates. A rotor winds as you move, storing energy for the hours when the watch rests on the nightstand. Turn it over and the exhibition back reveals the movement at work, a reminder that disciplined results are built on precise, repetitive motion rather than noise.

Engineered around how a serious watch should wear:

• Case: 40mm diameter, 12mm thickness for balanced wrist presence
• Bracelet: 20mm stainless steel bracelet, 220mm overall length
• Water: 10 bar / 100 meters, ready for swimming and daily use
• Movement: Japan NH35 automatic with hacking seconds

Care & Maintenance

Rinse the watch with fresh water after salt or chlorinated pools and dry with a soft cloth. Avoid hot water, saunas and strong impacts, which can compromise gaskets on any diver. Have seals and movement inspected at regular intervals to preserve water resistance and accuracy. Treated with this level of discipline, the watch will track years of work, travel and wins without losing clarity or integrity.

From the Corletaria Clocks collection - curated for men who see a watch not as jewellery, but as a tool that measures the distance between intention and execution. Each reference is selected from hundreds and kept only when it delivers reliability, restraint and real utility on the wrist.

Add this automatic diver to your rotation and join men worldwide who choose machines that match their pace, whether the day holds boardrooms, backstreets or blue water.
