Gold Black — black-tone case and bracelet, gold skeleton dial and Roman numerals. Strongest contrast — dark case with warm gold movement visible through the open dial.
Gold Blue — gold-tone case and bracelet, blue Roman numeral accents, blue hand details. The most colourful of the three — blue and gold across the skeleton layout.
All Gold — full gold-tone case, bracelet, dial frame and Roman numerals. Most uniform finish — single warm tone throughout.
The fully open dial removes the solid dial plate — the movement’s gear train, balance wheel, bridges and rotor are all visible from the front. Roman numeral hour markers sit on the movement architecture itself. The gold-tone movement finishing creates a warm mechanical aesthetic across all three variants.
At 10mm case thickness the 3210 is genuinely slim for a skeleton watch — most open-dial automatics run 12–14mm. The slim profile makes it more comfortable under shirt cuffs than typical skeleton dress watches.
The movement visible through the caseback is Miyota-marked with 21 jewels — consistent with the Miyota 8215 or 8205 family. Approximately 45-hour power reserve. Automatic winding via the rotor, no battery required. The Miyota 8200 series is globally recognised and serviced.
The bracelet uses raised geometric shapes on the centre links — a decorative construction that distinguishes the 3210 from plain three-link oyster alternatives. The geometric bracelet is part of the watch’s design statement alongside the skeleton dial. 316L stainless steel, spring butterfly clasp.
Synthetic sapphire with anti-reflective blue film coating on the inner surface. The coating reduces dial reflections, improving the skeleton movement’s legibility in mixed lighting. The blue tint is visible as a slight colour shift at certain viewing angles — characteristic of single-sided AR coating. Synthetic sapphire provides Mohs 9 scratch hardness.
At 172g the 3210 registers clearly on the wrist — the geometric bracelet and full metal construction contribute to the substantial feel. For buyers who want a watch with physical presence, 172g delivers that character.
50m covers daily use — hand washing, rain and brief splashes. Not suitable for swimming, diving or submersion. Avoid hot water and steam.
Skeleton dial buyers who want the automatic movement visible from the front at a wearable 40mm case. Slim skeleton buyers — at 10mm the profile is genuinely thin for an open-dial automatic. Gold accent buyers who want Roman numeral skeleton character in three distinct colour tones. Bracelet statement buyers who want the geometric centre links to contribute to the design.
