All watches sold in our store are internally inspected by a professional watch mechanic upon arrival and are only sold after being determined to be genuine, so you can use them with confidence.


When you purchase a watch, we will attach a new leather strap to it when you deliver it to you.
Please select the color you want from the order selection tab and place your order.
*For products that come with original watch straps or metal bands, the leather strap will not be attached and will be sent separately as a spare.
A special case for the watch will also be included with the shipment.

Please be sure to read the following information after purchasing an antique watch.

When selling antique watches at RESUME, we do not immediately hand them over to you when you place your order. Instead, we ask a professional craftsman to overhaul them (hereafter referred to as OH) and deliver them to you after the OH is completed. (This takes about 1 to 2 months.)

A professional craftsman with first-class watch repair technician qualifications will completely disassemble your watch, replace worn parts such as the internal gaskets, clean it, oil it, and perform a thorough overhaul, maintaining it to a daily accuracy of about ±1 minute.
When we deliver the machine, we will also send you our own overhaul certificate, which shows what kind of overhaul was performed, as well as photos of the machine being disassembled and maintained.

Of course, due to the nature of the product itself being a second-hand item, there is no guarantee that it will never break, but we ask for your understanding that we take this approach so that you can enjoy the original performance of the watch and use it with peace of mind in the future.

When you purchase a product, we offer a one-year warranty depending on the model. Even if the warranty period has expired, we will still repair the product for a fee. If there is no repair shop near you, please feel free to contact us.
