I'm actually still not sure if I should keep this one or sell... it's so nice and rare! This early 1940's ticks all the boxes. It's in great all original condition, it's the perfect size measuring 37,5mm ex crown and it has a super nice, rare original black gloss gilt dial. The thin Calatrava case fits the wrist perfectly and is ref 4915 with order number 2880. It was delivered to Africa in 1943. The Longines Cal. 12.68Z movement is super clean and just serviced. Attached is a period style nubuck strap (fixed lugs) with Longines buckle. Certainly one of the nicest oversize Longines Calatrava's around!
