Watchdives WD5512B ST2130 Sub Diver Watch

Watchdives WD5512B 40mm ST2130 Automatic Dive Watch

Refined quality. High-beat performance. Exceptional value.

The Watchdives WD5512B is a 40mm automatic dive watch designed to deliver a strong balance of finishing, mechanical performance and value.

At just 11.8mm thick, the stainless steel case maintains the solid presence of a mechanical diver without unnecessary bulk. An optimized low-slope rehaut creates a more open dial view and cleaner, more balanced proportions.

Crisp Bezel Action

The 120-click ceramic bezel delivers firm, precise mechanical feedback — one of those details that makes the quality of the watch noticeable every time you use it.

Careful case finishing and the slim profile further contribute to a more refined feel on the wrist.

High-Beat at the Heart

Inside, the Sea-Gull ST2130 automatic movement runs at 28,800 vph (4Hz), delivering the smooth sweep of a high-beat mechanical movement.

A sapphire crystal with AR coating, BGW9 lume, screw-down crown and upgraded clasp round out a practical and well-balanced specification set.

The WD5512B brings together refined finishing, a slim 11.8mm profile and high-beat mechanical performance at a price that makes the overall package especially compelling.

Quality you can feel. High-beat performance. Value that makes sense.
