Back in April, one of the Featured Watches was a Leopard 7220 from 1970, a high beat model with day and date window at the 12 o’clock position (https://sweep-hand.org/2012/04/13/this-weeks-featured-watch-30-the-leopard-7220/). The unusual day and date design, in one window, means that the changeover has to be instant at midnight.
Citizen also used this design in one of its Seven Star V2 models, this time using the 7280 movement. As a mid range model it runs at 21,600 beats per hour (the Leopard is 28,800), and has no fine adjuster on the balance. It hacks and hand winds though, like the Leopard. You can see where these two fit in the ’72 Leopard/V2 Family Tree’ via the link in the blogroll.
Here’s my well used example, with mid-blue dial:
The case back shows production in August 1970, and the case number is 4-780108 (as with the Leopard the 78xxxx indicates this particular day/date design), note the crown is in the fully out ‘hacking’/time setting position:
The 23 jewel movement, showing the movement number stamped in the usual place:
Crown is signed:
The Seven Star V2 models fitted in Citizen’s line-up just below the Leopards – in fact their retail prices overlapped to some extent. With solid and reliable movements, they were a nicely specified (hand wind-able and hacking, with quick set date) range of automatics.
