This is a new old stock vintage 1980’s BRICHOT dive watch. I’m guessing 80’s or late 70’s production. The large case is chunky and cool, measuring 40mm., 18mm. thick and 46mm. lug-to-lug-pristine. The original dial is awesome-massive, glowing Arabic luminous numerals and baton hands with red date. The turning bezel is “Pepsi” style. The movement is manual winding. The “Oyster” style bracelet has a flip-lock. We bought this from jeweller’s old stock. This is a great looking vintage watch-you are going to love it.
