This is a Seiko hand-wound watch, the Lord Marvel 36000. The model number is 5740-8000. It was overhauled on September 28, 2025, at a watch specialty store. It underwent disassembly and cleaning, light polishing of the case and crystal, replacement of the waterproof gaskets, and the installation of a new leather strap. The dial has no discoloration or stains, and the hands have no rust, so I believe it is in beautiful condition in those respects. It runs for over 40 hours continuously from a full wind. The daily rate has been adjusted to approximately +20 seconds. Although it has been overhauled, it is a very old product, so there are some scratches on the glass and case, but it is running without any problems. I am also listing Hamilton Jazzmaster and Ventura watches, as well as Longines watches. Please take a look.
