One of the better looking tuning fork Omega Constellation packages. All steel with Omega integrated bracelet 1177/1177 fitting wrists up to 190mm. The Omega movement in this watch was licensed from Bulova & ESA. Patent D2Y2, base stamped ESA 9162, Omega signed caliber 1250, Omega serial number on movement is 34824465. Case (manufacturer CB). Omega reference number 198.0006. Fully serviced (using battery Renata 344). 36mm diameter, from 1972. Turning into 2020, we have a selection of 3 of these watches, all with the same length bracelet (otherwise two of them had new owners already wearing them!). Needless to say, we are eagerly looking for bracelet links for them.
