1954 Bulova 23j USA mvmnt. 14k solid yellow gold case with white sunburst dial. I have been unable to positively identify this watch by model name or variant. Perhaps the expert eyes can help with that. It is however a gloriously beautiful example of whatever model this is. Case dia. is just over 32mm with an 11/16 strap width. Case is heavier than it looks to be. Allowing 2 full grams for the crystal (which i believe is more than actual weight) there is still over 14g of 14k gold in the case and case back. Heavier than other larger size cases I own. Supporting advert shows a model close to this but lugs appear different to me, perhaps that's just he artistic issue. Please have a look and weigh in.
Beautiful example Chris, well done! Based on the advert we also have this watch ID'd as an "I" variant.
