Superocean Heritage '57 Stainless Steel / Rainbow Boutique Limited Edition / Calf / Pin

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 9.99 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 42 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

A103701A1B1X1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. It was a limited edition. Introduced in 2020.

No-Date variation of Breitling's ETA 2892-based B10 movement. Automatic time-only movement supplied by either ETA or Sellita.
