AMSLEY Sub 300 cal. ETA 2827 / 1960s 46mm Double Rotating Bezel

— A certain unease in the exterior design —

A round dial set at the centre, wrapped in a 46mm square cushion case.

The eye loses its way along the outline and starts looking for the intent behind the construction.

A singular piece with the commanding presence of 46mm. An inventive double rotating bezel construction indicating dive time and city time. An asymmetry drawn by a crosshair and the Amsley / SUB300 markings. The dependable automatic Cal. ETA 2827, an improved version of the celebrated ETA 2824-2. A design where circle and square, sea and land, cross.

— A uniquely designed dial —

A crosshair runs across the dial, with the Amsley name at upper left and the SUB300 marking at lower right — a dial design that is unusual yet entirely orderly.

— What the double rotation means —

Inventive functionality from two bezels.

One works as a diver's bezel, totalling dive time.

The other is marked with city names and works as a simple world time.

Where the two uses cross, a quiet depth enters the construction.

— Cal. ETA 2827 —

Inside is Cal. ETA 2827, built on the Cal.2824-2 base with modifications including the calendar position.

Winding responds smoothly, transmitting the start of the drive to your fingertips.

— Where sight and use cross —

In this watch, use and form cross.

Diving and city time; a round dial and a square case.

A watch in which function and narrative live together.

A design that will have anyone who sees it guessing at the designer's intent — which is exactly why it embodies what a vintage watch should be.
