PRS Medium Manual Small Second
A 1950s pilot’s watch, with a Swiss movement from the 1980s
Built in the spirit of the watches worn by RAF pilots, at their original 36 mm size, and driven by a vintage hand-wound FHF calibre. Limited to 150 pieces.

01 — The dial
Read at a glance, day and night
Large Arabic numerals, luminous hands and markers: the dial takes up the codes of the RAF pilot’s watches of the 1950s, with a small seconds subdial at 6 o’clock. Matt black and uncluttered, it reads instantly, even at night.

02 — The movement
A vintage Swiss calibre
Inside beats a hand-wound calibre made in the 1980s by FHF, the Fontainemelon movement maker founded in 1793. A period movement that has become rare, and gives this watch all its character. A few turns of the crown each morning, and the small seconds hand comes to life.

03 — The size
36 mm, like the RAF originals
The RAF pilot’s watches of the 1950s measured around 36 mm. The PRS keeps that size, in an 11 mm case of matt stainless steel under an acrylic crystal, true to the era.
