Beautiful 1960s BUREN Grand Prix ultra-thin dress watch ref. 813802 - SS case with hooded lugs

Up for sale is a very nice Buren Grand Prix dress watch Ref. 813802. The original sunburst dial is still in good condition. The case is unpolished and in great shape plus the original crown. It is measure 33.3mm wide without crown and 36.2mm lug to lug, lug width is 17mm. Thanks to the ultra-slim profile: only 6.5mm in thickness, it wears larger. Inside is the Buren cal. 280, service history unknown but still keep decent time.
I'm asking 296 USD (or equivalent in Eur) plus shipping for it. Please see the below pictures for more details:
