For sale is an excellent condition Omega Seamaster "Kleerback" with a calibre 560. These watches are very uncommon and were made for the US market. You can read more information about this reference here and references within. The gold colored linen pattern dial is original is in fantastic condition. I will let the pictures do the talking, so included a number of high-res images. This is truly a stunning watch on the wrist. The case measures 34 mm the crown excluded. It is marked as 14K gold filled. There is some wear to the bottom of the lugs, probably from a metal bracelet fitted by the previous owner (see pictures without the strap), but other than that the case is in excellent condition with sharp bevels. If you are going to ask "where is the case bottom?" - then you haven't read the threads in the link . The movement is a calibre 560 and is marked as "adjusted 2 positions". The watch runs well and keeps good time. I timed it over 24 hours and it lost 1-2 seconds. The watch is currently on a plain brown generic leather strap. Given the relative scarcity of this reference, the condition of the dial, movement and case, my asking price is 1400$ - net to me. I will ship for free in the continental USA. Anywhere else will be determined by cost and will include insurance. I am happy to accept a return if the watch is not as described, within 3 business days of receipt. Please let me know if you have any questions. References are available upon request and you can also check out the "Seller Reviews" forum.
