A ref CK2015 is a rare watch... and this is honestly one the nicest I've seen! They are from the end 30's and feature a special case with 'bean lugs' and integrated crown. The special original dial is just mesmerizing with two tone silver and lovely patinated center and blued hands. The lovely steel case measures 35mm excl crown and is beautifully made. Movement is Omega's high quality Cal. 23,4  which has just been checked. Attached is a period Gey Freres bamboo bracelet (worth quite a bit in itself). Utterly beautiful and rare Omega!
