1970s 10K GF Mechanical Longines Ellipse

A wonderful 1970s 10K gold filled mechanical Longines Ellipse with a diamond dial. While this is not new old stock, it has been beautifully preserved and is in excellent condition with lovely patina on the dial. This special piece was a gift from Marie to her spouse, marking their 25th marriage anniversary as inscribed on the case back. It is a rare thing to find a piece from the 70s with original signed crown, inner and outer box (quite worn and damaged due to decades of storage), booklet, certificate of authenticity, and what appears to be the original JB Champion black velvet strap. The mesh bracelet is aftermarket and will come included as I feel it looks the part. Case is 10K Gold Filled.  Case size: 27mm  Lug to lug: 33mm (hidden lugs) Thickness: 7.5mm Movement: Longines Mechanical Cal. 528. Time only. Runs and keeps time within +34 seconds/day. Service history unknown. We always recommend you get your vintage timepiece a service from a professional watchsmith for optimal perform
