39mm Vintage Black-Bezel Automatic Dive Watch – NH35

A newly built 39mm vintage automatic dive watch with an individually aged matte-black dial, warm patinated markers and a clean no-logo design. A black timing bezel, brushed stainless-steel case and classic three-link bracelet give the watch the appearance of a well-used diving instrument while retaining modern mechanical construction.

The matte-black dial features large geometric hour markers, a prominent triangle at 12 o’clock and a framed date window at 3. The markers and hands have a mottled warm-gold finish that resembles naturally aged luminous material. Once charged by light, the luminous sections produce a green glow for improved visibility in darker conditions.

The dial, hands, case and bracelet are aged individually. The exact tone and distribution of the patina, surface marks and weathered finish will therefore vary slightly between watches. These variations are intentional and make every finished build subtly different. The watch is newly assembled and is not antique, pre-owned or refurbished.

Its solid 316L stainless-steel case measures 39mm excluding the crown, 13mm thick and 48mm from lug to lug. These proportions provide the wrist presence of a traditional dive watch while remaining compact enough for everyday wear. The standard 20mm lug width also allows the supplied steel bracelet to be replaced with a compatible leather, rubber, canvas or NATO-style strap.

A domed sapphire crystal protects the dial and provides the raised profile associated with vintage dive watches while offering greater scratch resistance than conventional mineral glass. The black 60-minute bezel rotates counterclockwise through 120 positive clicks, allowing elapsed time to be tracked without the risk of accidentally increasing the indicated time. A screw-down crown helps secure the case after winding, setting the time or adjusting the date.

The watch is powered by 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 runs at 21,600 vibrations per hour, uses 24 jewels and includes hacking seconds for more precise time setting. Approximate power reserve is 41 hours when fully wound.

The dial displays hours, minutes, seconds and the date. Pulling the crown into the time-setting position stops the seconds hand, while the intermediate crown position allows the date to be adjusted independently.

Each finished watch is checked on a timing machine in three positions before dispatch. The workshop acceptance targets are a measured rate within ±15 seconds per day, amplitude above 220 degrees and beat error below 0.6 milliseconds.

These measurements are acceptance checks rather than a guarantee of the exact daily rate on the wrist. Mechanical watch accuracy can vary according to position, temperature, available power reserve, magnetism and individual wearing habits.

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.
