1970’s YEMA “Sous Marine” Ref. 310021 Diver Blue Dial – FE Cal. 140-1C


Out of stock

Professionally restored and fully serviced in-house here at the Localtime Spa, this is a smashing Ref. 310021 “Sous Marine” from the historic French brand of YEMA, in a wonderful condition and with a sharp anthracite blue dial and black bezel that are a feast to the eyes. We have just had the manual-wind France Ebauches FE Cal. 140-1C serviced and it is ticking away happily with all functions working as they should. The 37mm chunky case [40mm including the crown] is in a great condition and we have lightly cleaned it to bring out the sparkle. The lovely orange/red seconds hand creates a wonderful contrast on the whole dial. We have made many photos, including snapshots from the restoration and some fun macro closeup shots. We have fitted this gorgeous watch with a same-period, NOS black leather rally-style strap and buckle, that we think matches the watch extremely well. As with all our watches that are serviced in-house here at Localtime, we offer a 6-month written warrantee from the date of purchase. Feel free to ask us any questions that you might have.
