Rolex | Submariner, Reference 5513, A stainless steel wristwatch with gilt dial and bracelet, Circa 1966 | 勞力士 | Submariner 型號5513 精鋼鏈帶腕錶，約1966年製

Introduced in approximately 1962, references 5513 and 5512 were the first Submariner models to be incorporated with crown guards. The present watch fitted with a gilt dial is particularly sought after by collectors. Eventually the reference 5513 was discontinued in approximately 1967. The dial is signed "Swiss T<25" at 6 o'clock that was first introduced by Rolex in 1964. The lumes react very nicely under UV light and the watch is preserved in very good condition considering its age.
