This is a Japanese version (uncommon) stainless steel 36.5mm. Omega Seamaster Chronometer. The OMEGA caliber 564 automatic movement sparkles after a recent cleaning. This watch is uncommon: being a larger than average Seamaster, The original bracelet is interesting-seldom seen, some stretch-will fit up to a 7.5 inch wrist. The bracelet has some subtle dings that are not detracting. Consider this to be a free bracelet, as we have not increased the price to cover its value. You can always wear this OMEGA on leather as well. The OMEGA crystal is signed (original) and the crown is original OMEGA and correct. The original dial looks great. The wide bezel frames the well-balanced dial. This is an ideal every-day-wearing watch!
