Purchased in Honolulu, Hawaii at Harry Winston. I haven't worn it in the past few years and it's been in storage. The battery died, so I took it to the Harry Winston directly-managed store in the Nihonbashi Mitsukoshi department store's watch floor for maintenance. They recommended not only a battery replacement but also cleaning the inside and replacing parts, so I had them do it (I will include the documents from that time, with the name section cut out). I also received polishing within the free service. Only genuine products can receive maintenance at Harry Winston's directly-managed stores, so this also serves as proof. Avenue C Mini The case size is approximately 31.1 x 16.0mm. The retail price exceeds 6 million yen. I am also listing another Harry Winston watch, but since I only have one box, I will include it with the first one that sells, unless you specifically don't need it. As this is a high-value item, returns and exchanges are not accepted to prevent substitution. Please refrain from purchasing if you do not understand that this is a used item.
