BERNY AM210M Automatic Sports Watch — Seagull ST2130 or PT5000, 38mm, 49g, 10ATM, Sapphire Both Sides

The BERNY AM210M is a 38mm Seagull ST2130 automatic sports watch — the lightest BERNY automatic at 49g. C3 super luminous Arabic numerals and hands, red seconds hand, date at 3 o’clock, sapphire crystal front and sapphire exhibition caseback, 316L stainless steel case at 11.5mm and 46mm lug-to-lug, carbon-fibre pattern leather strap with coloured inner lining, 10ATM water resistance. Available with either Seagull ST2130 or PT5000 movement. Seven colour variants.

Key Specifications

Variants — Seven Configurations

The AM210M uses a two-letter variant suffix system — first letter indicates strap base colour (A = black outer, BN = brown outer), second indicates accent colour:

AM210M-A-YE: Black strap / yellow accent lining AM210M-A-RD: Black strap / red accent lining AM210M-A-C: Black strap / blue accent lining AM210M-BN-YE: Brown strap / yellow accent lining AM210M-BN-RD: Brown strap / red accent lining AM210M-BN-C: Brown strap / blue accent lining

The coloured inner lining is visible when the strap curves on the wrist — a flash of red, yellow or blue at the edges.

ST2130 vs PT5000 — Movement Choice

The AM210M is offered with two movement options at the same price:

Seagull ST2130: Seagull in-house, 28,800 vph, approximately 42-hour power reserve. Chinese manufacture. Higher beat rate than Miyota 8215 family — produces a noticeably smoother sweep.

PT5000: 25 jewels, automatic and hand-winding. The same movement as the BERNY AM134MR.

Select size at checkout to specify the movement preference — confirm from the listing which size designation corresponds to each movement.

49g — The Lightest BERNY Automatic

At 49g the AM210M is the lightest BERNY automatic in the range — lighter than the AMT163M titanium at 56g (without strap) and the 2684VL ladies’ quartz at 23g (which is quartz, not automatic). For a 38mm sports automatic on a leather strap, 49g is exceptionally light. The lightweight comes from the 38mm case diameter at 11.5mm height — compact overall volume creates low mass.

Seagull ST2130 at 28,800 vph

The same caliber as the BERNY AM7110VM — Seagull’s in-house automatic at 28,800 vph, which is 4 Hz (8 beats per second). At this beat rate the seconds hand sweeps noticeably more smoothly than the standard 21,600 vph (6 beats/second) Miyota automatics, creating a more fluid visual motion. For buyers who specifically want the higher-beat Seagull in-house on a sports watch, the AM210M-ST2130 is the option.

C3 Lume on Arabic Numerals

The AM210M uses C3 Super-LumiNova (maximum output grade) on both the hands and the Arabic numerals — the full-number dial creates a higher total lume surface area than applied dot-marker dials. All twelve numeral positions glow simultaneously in darkness. Combined with the red seconds hand (which provides no lume but provides daytime contrast), the dial has both maximum legibility and visual accent.

Carbon-Fibre Pattern Leather Strap

The strap uses a carbon-fibre weave-pattern embossing on the outer leather surface — a diagonal grid texture creating the visual character of carbon-fibre composite without the material. The coloured inner lining (red, yellow or blue) creates a distinctive wrist appearance — the lining colour is visible at the strap’s curved inner edge. The strap uses contrast stitching matching or complementing the lining colour.

AM210M vs AM7110VM — Two BERNY Seagull ST2130 Automatics

Both use Seagull ST2130 in-house at 38mm:

Choose AM210M for the bold Arabic numeral sports character, colour accent strap system and lighter weight. Choose AM7110VM for the textured charcoal formal dial and calfskin nubuck strap.

Who Is the BERNY AM210M For?

The AM210M is built for:

• Lightest BERNY automatic buyers — 49g is the minimum automatic weight in the range
• Seagull ST2130 sports watch buyers who want the 28,800 vph in-house caliber on a sporty dial rather than a formal dress watch
• Colour accent strap buyers — the red/yellow/blue inner lining creates a specific sportive character
• Compact 38mm sports automatic buyers who want the smaller case without sacrificing 10ATM water resistance

How It Compares

vs. BERNY AM7110VM Seagull ST2130 — See comparison table above.

vs. BERNY AMT163M Titanium Miyota 8215 — AMT163M uses Miyota 8215 in titanium at 40.5mm/56g. AM210M uses Seagull ST2130 in steel at 38mm/49g. Titanium vs steel, different movement brands — both lightweight sports automatics.

vs. BERNY AM134MR PT5000 — AM134MR uses PT5000 at 41mm/200m with 3D wave dial. AM210M uses ST2130 at 38mm/100m with sports Arabic numeral dial. If choosing PT5000 movement variant: same movement, different dial and water resistance.
