Angelo Mangiarotti, T1

‘T1’ clock by Angelo Mangiarotti for Secticon, featuring the original Portescap Swiss electromechanical movement, 1956.

Fresh from the clockmaker’s workshop, restored, serviced and adjusted – as good as new, just as it was 70 years ago.

Note how the hour markers on the dial become progressively thicker as the hours pass. At 1 o’clock, the hour marker is just a thin line, whereas at 12 o’clock it reaches its maximum thickness. Angelo Mangiarotti conceived this dial design to visually represent the passing of time.

Angelo Mangiarotti (1921–2012), Italian architect and industrial designer.

Portescap SA (formerly ‘Porte-échappement universel SA’, La Chaux-de-Fonds, 1931–2020), known for marketing the ‘Incabloc’ shock-absorption system found in almost every mechanical watch. After several restructurings, Incabloc SA was finally acquired by Rolex, Richemont and Patek Philippe in 2024.

The movement in this watch is known to have a weak point ( escapement), which ceases to function after decades; consequently, the majority of T1 watches currently on the market are out of working order. Or the original movement has been replaced by a quartz movement. We had the original movement restored in 2026 by a Neuchâtel-based watchmaker specialising in the restoration of antique watches. The restoration is documented with photographs and an invoice.
