1970s NOS Glycine Vacumm High Frequency Mechanical Watch 343.121 Day/Date 42mm S.S.

Watch Overview

Offered here today is an interesting and collectible timepiece: a vintage NOS (New Old Stock) Glycine Vacuum High Frequency automatic wristwatch, reference 343.121, dating from the 1970s.

This self-winding watch is powered by a Swiss automatic movement and features a sweep seconds hand and a day/date display with quick-set function.

The "Vacuum" designation used by Glycine referred to the specially engineered case construction designed to provide enhanced protection against air, dust, and moisture. The system was marketed as offering improved sealing and durability for the movement.

The original silver-tone dial is accented by applied baton hour markers, a printed minute track, and matching hands with luminous inserts. The day (in Spanish) and date display is positioned at the 3 o’clock position.

It is housed in a striking 42mm tonneau-shaped stainless steel case. According to period Glycine advertising, the case construction emphasized resistance to water, air, and shocks.

This example remains in New Old Stock condition and is fitted with a brand-new gray two-piece rubber strap.

Fully inspected and authenticated, the watch is running well and is ready to wear and enjoy.
