Military or Doctors Watch


Rare Rolex Reference #3121 "Mid-Size" Model

These scarce #3121 watches were produced in the "Oyster Royal" and the "Royal Observatory" models. Both are extremely scarce & quite collectible, ESPECIALLY if they are in near mint condition!!!


Near MINT Overall Condition, We just released this from our shop where it has been completely serviced and has new gaskets & seals, a new Rolex "Twin-Lock" factory crown, and Premium High Grade Exotic Genuine Ostrich padded & stitched strap



100% All Original & 10 time Factory Signed and Hallmarked



High Grade all original Rolex stem-wind and stem-set movement. 


Stainless Steel Rolex "Oyster"   Water resistant case with new Rolex signed & hallmarked screw down "Twin-Lock" crown. (this is a "mid-size" watch measuring aprox 30mm wide not counting the stem & crown by 36mm lug to lug in length)


Mint Condition Rolex 2-tone Silvered Dial with black enameled  Rolex Logos, center dial trim, outer minute track and the "Doctors" outer seconds indicator with sweep seconds hand for checking pulse.


Please note that wrist watches in the 1930's & 1940's either had no seconds hand at all, or used a subsidiary seconds register at the 6:00 position. Wrist watches just never came stock with "Sweep" second hands thus making this timepiece very  SCARCE


The hour markers and hands are luminous & still in excellent condition.

We were only able to locate VERY few other Reference 3121 Rolex watches on the Internet, the prices were $2000-$2800 for ones in only poor to average condition and well over $3600 for ones in nice condition, and even that nice condition watch did not have the mint condition Sweep Second Two-Tone "Doctors" dial and they were in nowhere close to the mint condition of this one!! Act quickly on this one,,, it will not last long!!



Near Mint Overall Condition
