Stunning Citizen Cosmotron Electronic from 1975, in excellent original condition.
The movement is an electro mechanical one,. The 7803 Cosmotron calibre has an electronically controlled balance, it runs at 36,000 bph. It has a unique day / date quickset since they can be set by pushing the crown with either 12 at top (for the date) or at bottom (for the day). Clever.

The pusher at 8 o’clock stops the watch.

Nice grey dial, sword hands and metal hour markers. Days in Kanji and English and date at 3. The stainless steel case is 38 mm wide, with a screw back. Original CTZ crown. The bevelled glass crystal is original and in very good condition.

The watch will be delivered with its original “Cosmotron” signed stainless steel bracelet.

Vintage watch with unknown history but checked and cleaned (2022/01). Water resistance non tested.

Year of manufacture

The brand

Citizen is the second most important japanese manufacturer. The brand has often been in the shadow of its huge competitor Seiko but often offered something more than Seiko for an equivalent price. As a result, Citizen produced some very interesting models, technically very advanced and with sometimes unusual designs.
