This is a SEIKO LORO MARVELA36000. It was overhauled in September of this year, and the original mainspring was replaced. It comes with a six-month warranty, but the personal information section will be cut out. The time difference is within the range of an antique watch and is running. The crystal has no scratches, and the dial has no burn marks or stains, making it a beautiful piece for an antique watch (in my personal opinion). Manufactured in June 1967. ● Case size: 35mm wide, 42mm long, 10mm thick ● Lug size: 19cm ● New band
