The Only Titanium Automatic in the BERNY Range

The AMT163M is the only BERNY model at Jewelry Addicts combining a titanium case with an automatic movement. All other BERNY titanium watches (T2566M, T2567M, T2556M, T2576M) use quartz. The combination — 56g titanium case + Miyota 8215 — creates a watch lighter than most steel automatics at comparable case sizes while retaining the mechanical movement character.

For context: a standard 40mm steel automatic on a nylon strap typically weighs 80–110g. The AMT163M at 56g is approximately 30–50% lighter at the same size.

Miyota 8215 in Titanium

The Miyota 8215 is the same caliber used across the BERNY AM339M compressor and AM151M diver — a proven automatic at 21 jewels, 21,600 vph, hacking seconds and hand-winding. In the AMT163M it operates within a titanium rather than steel case. The caseback is solid titanium rather than sapphire exhibition — the movement is not visible, consistent with a field watch rather than a dress watch.

Field Watch Dial Layout

The AMT163M uses the standard field watch dial hierarchy:

Primary: Large Arabic numerals at the hour positions — direct reading, high contrast, legible at a glance.

Secondary: Inner 24-hour scale — a second ring of smaller numerals showing the 24-hour equivalent of each 12-hour position. Useful for international time zones and military/24-hour timekeeping.

Red seconds hand: The contrasting seconds colour confirms the movement is running and provides a visual reference point separate from the hour and minute hands.

Date at 4–5 o’clock: Positioned outside the standard 3 o’clock location — slightly unusual, keeps the date from conflicting with the Arabic numeral at 3.

AR Sapphire — Internal Coating

The sapphire crystal has an internal AR (anti-reflective) coating — on the underside of the crystal facing the dial. Internal AR reduces the reflection from bright overhead light that can create a whitish glare obscuring dial content. On a field watch used outdoors, AR coating meaningfully improves dial legibility in direct sunlight compared to uncoated sapphire.

10ATM on a Titanium Field Watch

100m water resistance combined with titanium construction creates specific practical suitability: titanium’s corrosion resistance in saltwater environments means the AMT163M maintains seal integrity in marine conditions better than steel watches with chromium oxide passivation. For buyers who use a field watch near the ocean or in high-humidity outdoor environments, titanium plus 10ATM is the appropriate specification.

AMT163M vs T2566M — Two BERNY Titanium Watches

The two most-compared BERNY titanium models:

Choose AMT163M for automatic movement, 10ATM, 24-hour inner scale and the larger 40.5mm field watch format. Choose T2566M for lighter weight (40g), VH31 sweep-second quartz character and the smaller 37.5mm compact format.

Who Is the BERNY AMT163M For?

The AMT163M is built for:

• Titanium automatic buyers — the only BERNY titanium automatic at Jewelry Addicts
• 24-hour inner scale buyers who want the dual-time reference on an automatic field watch
• Yellow dial titanium buyers — AMT163MS-YE / AMT163M-YE are uncommon in titanium automatics
• 10ATM nylon strap buyers who want the quick-release nylon on a lightweight titanium field automatic

How It Compares

vs. BERNY T2566M Titanium VH31 — See comparison table above.

vs. Steelflier SF751 NH35 — Steelflier uses NH35 at 40mm/200m in 316L steel at ~90g on leather. BERNY uses Miyota 8215 at 40.5mm/100m in titanium at 56g on nylon. Different materials and water resistance levels — choose Steelflier for 200m; choose BERNY for titanium and lighter weight.

vs. San Martin SN007G V4 — San Martin uses NH35A at 41mm/200m in steel. BERNY uses Miyota 8215 at 40.5mm/100m in titanium at 56g. Different movement brands and water resistance — choose San Martin for NH35A and 200m; choose BERNY AMT163M for titanium and lighter weight.
