Vintage 1970s Kramer Jump Hour Mechanical Digital 17J Swiss Watch 39mm Space Age

About this watch

A 1970s mechanical "digital" watch: instead of hands, the time is read from rotating discs, with the hour in a square window and the minutes on a curved disc beside it, plus a date window below. The dark grey dial is signed Kramer and "17 Jewels Incabloc", with fine horizontal lines that give it an instrument-like look under a high-domed crystal.

The 39mm gold-tone case has a broad cushion profile with a deeply recessed display window, a true Space Age shape. The stainless-steel snap caseback is marked Waterproof, Swiss Made and Mod. Depose. It is fitted on a brown leather strap.

Brand heritage

Kramer is a little-documented Swiss watch name of the 1970s. Like many smaller Swiss houses of that decade, it answered the fashion for early electronic digital watches with mechanical jump-hour and disc-display models, which are now collected for their bold Space Age design.

Why this one is special

• Mechanical jump-hour disc display, no electronics
• Dramatic 39mm Space Age cushion case
• Swiss 17-jewel movement with Incabloc shock protection
• Date display beneath the time windows

Condition

Substantial honest vintage wear, including scratches, marks, discoloration and areas of finish loss to the case. The crystal and caseback show scratches, and the dial shows age-related marks visible in the photos. The rotating date display occasionally sticks, so the watch should be considered in need of adjustment or servicing for dependable operation. The strap appears to be a later replacement. Water resistance has not been tested and should not be relied upon. Please check all photos carefully as they are part of the description.
