The Firshire collection is one of the most famous in Paul Picot's production, having hosted a variety of watch movements over the years, from the classic three hands to the chronographs, up to the ultra-thin ones. The Double Moon Phase version indicates the moon phases (positioned at 9 o'clock) for both the Earth's hemispheres, North and South. The blue dial is complemented by Dauphine hands, applied geometric indices, small seconds at 6 and a circular date window at 3. 41 mm steel case is paired with an alligator strap with folding buckle, and the dial is protected by an anti-reflective sapphire crystal. The watch is powered by the PP 1260 caliber, a self-winding mechanical movement visible through the sapphire crystal porthole on the case back. Waterproofing is guaranteed up to 5 atmospheres of pressure.
