V. 80s Seiko Diamond & MOP 50m Watch

This vintage watch by Seiko comes to us from the 1980s and requires a new battery. It has not been tested for functionality but the exterior is in good condition overall, suggesting the piece was well taken care of. The face is a beautiful mother of pearl with gold tone hands and a date slot in place of the 3. There is a roman numeral at the top (12) with a small diamond in place of the other numbers (1-2, 4-11). The watch is water resistant to 50 metres (as marked on the face).The backing is stainless steel, and the back is also marked "SAPPHIRE CRYSTAL, 7N82-OBR0 [R2], MOVEMENT JAPAN, (SN) 464058" with the serial number dating the watch's creation to June 1984. The end pictures show the double fold over clasp as well as the markings on either end. Aside from the battery issue, the watch has normal wear. There are superficial marks in the band metal as well as the metal around the face. The watch would benefit from a deep clean when serviced, but is still eye catchingly beautiful as is. I believe there is supposed to be a faceted stone on top of the crown, but pic 4 shows it is missing. Though there are marks in the metal, there is minimal marking in the glass face. Length: 19cm / 7.5" Length (open): 25cm / 9.75" Face dimensions (including crown and lugs): 25.5x28mm Weight: 55.76g Love the piece but not the price? Make an offer! (Watch body is good condition overall but I've marked the piece "fair" as it is missing the battery)
