Vintage Aviation Character. Hand-Wound Chronograph. Sapphire Protection.

The TOPHILL 40mm 1963 Chronograph captures the unmistakable character of classic military aviation watches and pairs it with a modern enthusiast-friendly specification.

At its centre is the Seagull ST1901 mechanical chronograph movement, housed in a compact 40mm case and protected by sapphire crystal.

The result is a watch with genuine mechanical interaction, vintage pilot-watch proportions and a dial designed to look like an instrument rather than a fashion accessory.
