Next year, beginning at SIHH, Audemars Piguet will celebrate 25 years of making the sportiest version of their famous Royal Oak collection: the Offshore.

So far the Le Brassus watchmaker has revealed three new versions including a re-edition of the original Royal Oak Offshore Chronograph from 1993, in stainless steel with a blue “Petite Tapisserie” dial.

The other two contemporary styled Royal Oak Offshore Chronograph Tourbillons, one in steel and the other in 18K pink gold. Each is limited to 50 pieces.

These timepieces are inspired by previous models and feature a redesigned movement that was made exclusively to pay homage to 25 years of the Royal Oak Offshore collection.

The hand wound movement, caliber 2947, beats at 3Hz (21,600 vph), measures 39.78 mm x 11.60 mm, consists of 353 parts, 30 jewels, and has a power reserve of 173-hours.

An open-worked dial reveals the movement, with a 60-second tourbillon visible at 9 o’clock on the dial side. The dial has significant depth to it and is surrounded by an octagonal bezel with hexagonal screws, a signature of the brand, although there are unique cut-outs in the bezel in the same angular shape that create a very distinctive look. And instead of metal and rubber, the crown and pushpieces are now crafted in ceramic.
