These 31mm watches are the rarities of the size chart, while the 26-34-36 are common, the 28 and 31mm's are quite hard to get throughout the year. This watch is well taken care of and comes on an oyster bracelet in good condition. The watch was worn and shows superficial signs of wear, can be polished on request.
