UMF - 1950-1959

Blind pocket watch

Type:
Mechanical pocket watch (Open-Face), hand-wound, simple execution without complications (no small seconds visible, but typical for the “Regular” model).
• Model name:
UMF Ruhla Regular (the most common variant with this plain dial and the distinctive dots at the 5-minute markings).
• The caliber is the legendary UMF 83-31 (also called M1), a robust pin-lever movement (pin-pallet escapement), that was built in various variants from about 1923 to 1990 — one of the most durable movements of all time.
