I took a pic of my old man's watch while we were having lunch. Seen him wearing this more often lately compared to his 41 Presy.. i think its a computer dial Datejust (i could be wrong) but not sure the reference number and is that a factory diamond bezel... my mom have same watch but smaller, i believed it's a pair/couple watch as mom once told me it's their Golden Anniversary watches.
yeah..this is probably the one my mom have..n my dad's one is the 40mm version..
