OUPINKE 3169 Guilloché Dial Automatic Watch – NH36A, Day-Date, Tungsten Bracelet, 50M

The OUPINKE 3169 is a 41mm round automatic dress watch with a radial guilloché-pattern dial — concentric wave engraving across the full dial surface, combined with crystal-set indices and gold-tone Roman numeral markers at the quarter-hour positions. Seiko NH36A movement with day-date at 3 o’clock. Synthetic sapphire crystal. Tungsten and stainless steel diamond-cut bracelet with butterfly double clasp. Swiss luminous. 11mm thick, 165g, 50M water resistance. 5 dial variants: white, grey, blue, green, black — all with two-tone silver/gold bracelet. CE RoHS certified.

Key Specifications

Seiko NH36A — Movement

The NH36A is a Seiko-manufactured Japanese automatic movement — the day-date variant of the NH35A. 24 jewels, 21,600 vph, bidirectional automatic winding, manual winding, hacking seconds. Power reserve approximately 41 hours. The NH36A is the same caliber used in the OUPINKE 3171 and 3200 — the 3169 shares the same movement spec but a distinct dial design.

Image 5 shows the import customs manifest and invoice confirming Japanese-origin movement import — the listed items include “82S0-21G型” and similar Seiko caliber codes, confirming the Japan-manufactured movement claim.

Guilloché Dial

The 3169 dial uses a radial guilloché pattern — concentric spiral and wave engraving machined across the full dial surface. This is a traditional watchmaking decoration technique applied to add light-scattering texture to an otherwise flat metal dial. The radial lines emanate from the centre and refract light differently at varying angles, giving the dial a shifting depth under movement. At different lighting conditions the dial reads as anything from near-solid white to a complex layered surface.

The dial decoration sits behind a layer of crystal-set indices — flower-shaped crystal stones set at each hour position — combined with Roman numerals in gold tone at the three, six, nine, and twelve o’clock positions. The OUPINKE wing logo appears as an applied element at 12. “Automatic” is printed in italic script at 6 o’clock.

Dial Variants

White — guilloché white dial with gold-tone hands and indices. The most legible and formal configuration. Maximum contrast between the white radial surface and the gold markers.

Grey — deep grey guilloché. Subtle and understated; suits business and smart-casual contexts.

Blue — electric blue guilloché surface. High visual presence; the crystal indices provide strong sparkle contrast against the blue base.

Green — deep forest green guilloché. A dress watch colour gaining significant market traction — distinctive without being loud.

Black — dark guilloché. The highest contrast variant for the gold indices and hands.

All five variants share the silver and gold two-tone bracelet — the gold centre links run the length of the bracelet as a colour accent.

Tungsten and Stainless Steel Bracelet

Diamond-cut pyramid-faceted tungsten carbide and stainless steel links — the same bracelet family used across the OUPINKE dress watch range. The 3169 bracelet uses a silver and gold two-tone pattern with alternating gold centre links. Butterfly double clasp, stamped OUPINKE logo, push-button release. Bracelet circumference 20cm. Link removal via standard pin tool. Weight 165g — lighter than the 3200 (183g) due to the smaller round case vs tonneau.

Swiss Luminous

Swiss luminous powder on hands and dot hour indices — green emission in darkness. The lume image in the product photos shows the full hour ring, hands, and centre dot markers illuminated. The crystal-set indices do not carry lume — the dot lume markers between them provide the hour position reference in low light.

50M Water Resistance

50M / 5ATM via sealed gasket construction. Suitable for splash, rain, handwashing, cold bathing, and swimming. Not suitable for warm or hot water, steam, snorkelling, or diving. Do not operate the crown while submerged.

Certifications

The 3169 holds CE RoHS certification — confirming compliance with the EU RoHS Directive on hazardous substance restrictions in electrical and electronic equipment. This confirms the watch is free from restricted hazardous substances for sale in EU markets.

How the 3169 Compares to the 3171 and 3200

All three are Geyashi Series dress watches sharing the NH36A movement, tungsten bracelet construction, and 50M water resistance. The difference is the dial:

• 3169 — guilloché radial pattern dial with crystal-set indices. Most ornate dial surface.
• 3171 — sunburst dial with diamond crystal indices. Cleaner, more classic.
• 3200 — tonneau case with sunburst dial. Different case shape; same movement and bracelet spec.

All three are 41mm round except the 3200 (40.5×37.5mm tonneau). Browse the full OUPINKE watches collection for the complete range.

FAQ

What movement does the 3169 use? Seiko NH36A automatic — 24 jewels, 21,600 vph, day-date, hacking, manual winding. Japanese manufacture. Power reserve approximately 41 hours. The same movement as the OUPINKE 3171 and 3200.

What is the guilloché pattern on the dial? Guilloché is a precision-machined engraving technique that creates repeating geometric patterns across a metal surface. On the 3169, it is applied as a radial concentric wave pattern across the full dial, which scatters light differently at different viewing angles.

Are the dial indices real crystals? The flower-shaped stones set at each hour position are synthetic/simulated crystals — decorative stones, not precious gemstones.

Which dial colour is most popular? White and blue are the most broadly versatile. Green and black are the most distinctive. Grey is the most understated.

Is the crystal sapphire? Synthetic sapphire — Mohs 9, scratch-resistant under normal daily wear.

Is it waterproof for swimming? Yes — 50M / 5ATM, suitable for cold bathing and swimming. Not suitable for warm water, steam, snorkelling, or diving.

How does this compare to the 3171? Both use the NH36A movement and tungsten bracelet on a 41mm round case at 11mm thickness. The 3169 has a guilloché radial dial with crystal-set indices; the 3171 has a sunburst dial with diamond crystal indices in a slightly different arrangement. The 3169 is 165g vs the 3171 at 135g — weight difference is likely from case construction variation. Choose based on dial preference.
