Is there a case and dial with this one?
Nice movement though.
In reply to Is there a case and dial with by bobbee
yes. The watch is on a Speigel stainless steel watch band. It is complete. The crystal is alittle scuffed up.
Sorry, the pic of the case did not come up when I made my first post!
Looks like N0 for 1970 on the movement, and this tallies with the movement model, not seen on this site before 1967, and several watches use this movement well into the 1970's.
What letter and number does it say on the case back?
After looking in the 1970's ads, I have found a model and variant for your watch.
The CONCERTO "DC". 1973 advert.

1970 sounds right. Watch does seem to match the Concerto DC ad. Good catch Bobbee.
Agree. Good find.
The case
has Z2556400 on the outside.
Looks to be in line Bobbee... I'd concurr with the Concerto DC.
'CONCERTO'
Dial and case color combinations in play.

'DC' - Gilt markers on Champagne Dial, according to the ad referenced for the ID. There is no mention of the Case color although I'd suspect the 'DC' variant is Yellow.
The subject appears to be a White Case with White indecees on White or Silvered Dial?
