Recién llegado y ya es mi diario. La combinación de colores es muy original y el cuarzo va al segundo. Trato excelente por WhatsApp.

THE TACHYMETER SCALE

An on-board calculator

The outer ring is not decoration. Time a kilometre and the hand shows you the average speed: 500 at the top, 60 at the bottom, twenty-two values. This is how the pace of a stage was measured before electronics existed, and this is how it still works.

THE DIAL

The red sector

A counter split into two colours is not an ornament: it is a limit painted in. Someone worked out how far the engine could hold and left it written on the dial, so as not to have to remember at two hundred an hour.

First it is drawn

Twelve spokes, two counters and a ring. Everything else comes afterwards.

in the present

The Strum Series 113 is drawn in the language of the chronographs of the 1960s and ’70s: cushion case, twin counters, tachymeter scale, the colours of the track. It copies no particular watch. It pays tribute to the pioneers of that era — drivers, mechanics, engineers, designers — and each model in the series carries the craft of one of them.
