It is a registered design model that features a three pieceCHROMED STEEL case that provides with glass cover of back lid. This watch was converted from pocket watch.CHROMED STEEL case, new custom made, fantastic, build specially for this excellent OMEGA movement. The swivel lugs are in great condition while the winding crown is in very good shape and operates properly. The case hasMINERAL glasses on the front and back side.

 

  

Peeking inside via the glass lid I find is a clean manual wind and QUALITY – 21 JEWELS nickel-plated lever escapement movement with GENEVA PATTERN,RAISED & SCREWED THREEFOLD in ROSE GOLD CENTER JEWEL CHATON, FOUR SCREWED in GOLD JEWEL SETTINGS, SWAN NECK MICROMETER REGULATOR & BLUE BREGUET BALANCE SPRING.

 

To enhance the power coming through the train, the center wheel is provided with a chaton jewel, which is mounted in rosé gold and is screwed threefold. Only jeweled holes minimize reliably the friction due to enormous driving power of the mainspring and consequently the going barrel. The screwed chaton allows the precise adjustment of the wheel and the quick change of the bearing jewel if necessary. The further wheel arbors are protected by jewels.

 

The number of jewels used in watch movements increased over the last 150 years as jewelling grew less expensive and watches grew more accurate. The only bearings that really need to be jeweled in a watch are the ones in the going train - the gear train that transmits force from the mainspring barrel to the balance wheel - since only they are constantly under force from the mainspring. The wheels that turn the hands (the motion work) and the calendar wheels are not under load, while the ones that wind the mainspring (the keyless work) are used very seldom, so they do not wear significantly. Friction has the greatest effect in the wheels that move the fastest, so they benefit most from jewelling. So the first mechanism to be jeweled in watches was the balance wheel pivots, followed by the escapement. As more jeweled bearings were added, they were applied to slower moving wheels, and jewelling progressed up the going train toward the barrel. A 17 jewel watch has every bearing from the balance wheel to the mainspring barrel jeweled, so it was considered a 'fully jeweled' watch. In quality watches, to minimize positional error, capstones were added to the lever and escape wheel bearings, making 21 jewels.

 

The movement is signed OMEGA WATCH Co – SWISS – 21 JEWELS ADJUSTED – 5 POSITIONS. Also is signed the movement serial number #3,821,355. This serial number dates this watch to 1911 as per published production numbers.

 

 

This beautiful wristwatch has the ORIGINAL OMEGAmovement in an excellent status which was very well saved, considering age of this watch. Mechanism has been recently serviced to ensure it winds and sets smoothly while keeping great, accurate time.

  

 

It comes complete with a new 22mm black high quality strap genuine leather with matching STAINLESS steel buckle for a most excellent look.

This rare watch winds and set smoothly while keeping very good, accurate time.

Because of the vintage nature of the watch I cannot guarantee its absolute time keeping accuracy even if they are in good running condition and in some rare occasions may require additional adjustment.
