Hi,
Sorry for my late reply.
Please find attached some pics.
Any information on this model is much appreciated
Very nice indeed!
Cal 3600 automatic. In-house Lemania design. Basis is the cal 3000 HW which again is based on the cal S27 basis. Robust and well designed with Breguet spiral and full rotor winding.
For those interested you will see that the movement shares the unique "catch device" for the hairspring.
This is a "Lemania only" design feature you will recognize from the Omega/Lemania cal 320/321.
I have a catalog from 1956, but the ref is not listed. If you provide a serial number I could try to make a qualified guess on age.
The Lemania cal 3000 family, at least, consisted of the following calibers:
• Lemania 3000: sub second, 17 jewels, Breguet spiral.
• Lemania 3010: sub second, 21 jewels, Breguet spiral.
• Lemania 3015: sub second, date, 17 jewels, Breguet spiral.
• Lemania 3040: sub second, 21 jewels, Breguet spiral, glucydur balance.
• Lemania 3050: sweep second, 15/17 jewels, Breguet spiral.
• Lemania 3060: sweep second, bridge over center second drive, 17 jewels, Breguet spiral.
• Lemania 3065: sweep second, bridge over center second drive, date, 17 jewels, Breguet spiral.
• Lemania 3100, 3110: sub second, 17 jewels flat hairspring
• Lemania 3150: sweep second, 15/17 jewels flat hairspring
• Lemania 3160: sweep second, bridge over center second drive, 15/17 jewels flat hairspring
• Lemania 3170: sweep second, bridge over center second drive, 15/17 jewels flat hairspring
• Lemania 3300: sub second, “triple calendar”: day, date, month, 17 jewels flat hairspring. Same as Omega cal 380 (381 without moon-phase indication).
• Lemania 3535: sweep second, 15/17 jewels flat hairspring
• Lemania 3540: sweep second, bridge over center second drive, 15/17 jewels flat hairspring
• Lemania 3600: Automatic version of caliber 3000, sub second. 17/21 jewels, Breguet spiral
• Lemania 3610: Automatic version of caliber 3000, sub seconds. 17/21 jewels, Breguet spiral
• Lemania 3615: Automatic version of caliber 3015, sub seconds. 17/21 jewels, Breguet spiral, Date function.
