39.5mm Vintage 369 Automatic Dive Watch – NH35

A newly built 39.5mm automatic dive-style watch combining the functional profile of a traditional diver with the distinctive clarity of a 3-6-9 dial. Its individually aged matte-black dial, warm vintage-tone lume, faded black aluminium bezel and weathered stainless-steel exterior create the character of a time-worn tool watch, while a modern TMI NH35 automatic mechanical movement provides practical everyday operation.

The black dial features large Arabic numerals at 3, 6 and 9 o’clock, a triangle marker at 12, clear hour markers and a contrasting outer minute track. The combination of a field-watch-inspired dial and a unidirectional timing bezel gives the watch a distinctive hybrid tool-watch appearance. There is no visible date window, keeping the hours, minutes and seconds display balanced and uncluttered.

Every dial and exterior is aged individually. The tone and distribution of the matte finish, warm lume, faded bezel and weathered surface marks will therefore vary slightly between watches. These differences are intentional and form part of the design. The watch is newly assembled with an intentionally aged finish; it is not antique, pre-owned or refurbished.

The unidirectional timing bezel contains a faded black aluminium insert with a softened appearance that complements the aged dial. It can be rotated counterclockwise and aligned with the minute hand to measure ordinary elapsed intervals. The timing bezel is a functional mechanical feature, but it does not make the watch suitable for underwater diving.

The 316L stainless-steel case measures 39.5mm excluding the crown, 16mm thick and 47.5mm from lug to lug. Its standard 20mm lug width accepts many compatible replacement straps. A domed mineral glass crystal protects the dial and creates the pronounced curved profile associated with older tool watches. The screw-down crown helps keep the case securely closed after winding or setting, and the supplied aged three-link steel bracelet continues the weathered finish.

Inside is a Time Module Inc. TMI NH35 automatic mechanical movement. It winds through wrist movement and can also be wound manually through the crown. The movement uses 24 jewels, runs at 21,600 vibrations per hour and provides hacking seconds for more precise time setting. Approximate power reserve is 41 hours when fully wound. No battery is required.

Each finished watch is checked on a timing machine in three positions before dispatch. Workshop acceptance targets are a measured rate within ±15 seconds per day, amplitude above 220 degrees and beat error below 0.6 milliseconds. These readings are acceptance checks rather than a guarantee of the exact daily rate on the wrist.

Every completed watch is individually water-resistance tested after final assembly to 20 ATM, equivalent to 200 metres of static pressure.

This rating should not be interpreted as a recommendation to dive to a depth of 200 metres. Our watches are not represented as ISO 6425-certified professional diving instruments and are not recommended for deep or professional diving.

Always keep the screw-down crown fully secured around water and never operate it while the watch is wet or submerged. Water resistance is not permanent, so periodic pressure testing is recommended, particularly after servicing or a strong impact.
