Mid-1950s International Watch with Cal. 8521, Waterproof Automatic Date, Silver Dial

This watch features a highly sought-after bar index design. The waterproof case, with its rare long-lug design seen occasionally in the 1950s and 1960s, has a well-balanced size of 34mm in diameter and a 20mm lug width. The case also has a distinctive presence, thanks to the volume typical of an automatic movement.

The silver dial, paired with applied bullet-shaped indices and dauphine hands, offers a simple yet timelessly refined aesthetic. The centrally positioned date display and domed dial further enhance its vintage charm, capturing the distinctive character of this era.

Equipped with the in-house automatic movement Cal. 8521, this timepiece is a remarkable example of mid-century horological craftsmanship.
