Rotary 9k Gold trench watch 1900's - Case #197018


An Officers WW1, 9k Gold Trench Watch which was also sometimes known as a wristlet. This particular one comes with subsidiary seconds dial at 6 0'clock, "Red 12", stepped porcelain dial which you do not often see. The dial has some hairline marks on it but they are only obvious through a loupe. The watch dates to circa.1924 from the hallmark, there are also a London importers marks and a sponsor’s mark of "SD", which is Sylvain Dreyfuss of London. Dreyfuss began importing Rotary watches in the United Kingdom in the very early 1920's and did not start using the Rotary wings or logo's until after 1925 when Rotary registered it as their trademark. It is likely that this watch is possibly an early unbranded Rotary, but we cannot be certain as even the movement, apart from "Swiss Made" has no markings or caliber reference. If you wish to read more about the Importers "SD" then please see here.

This is a fantastic watch that has all its Hallmarks including the letter "i" for date c.1924 and London Import Assay mark but no Case or movement signatures that we can find. 

Back in the day, small pocket watch movements were being converted to wrist watches as men had finally decided that carrying a pocket watch was too hard to read particularly whilst in the trenches. WW1 was the beginning of wrist watch usage by men. Called trench watches or wristlets, as the soldiers could tell the time with one hand while carrying their weapons and kit in the trenches.

This particular watch will likely have been made in the style of an officer's watch as the case is made of 9ct gold and would have cost a lot of money in its day!

The dial is in very good condition given its age and probable history and we have left it as is, as we did not wish to try and refurbish it at all as we feel this would greatly affect its character and also value.

The watch case is a three-piece case with hinged back and front and both parts shut perfectly well and the hinges are in excellent condition as is the gold case itself having had a light and gentle polish. The watch is running strong but a little slow so will be sent for a full overhaul/service before it is delivered to you!  

The crystal is in good condition and there is at present no strap attached but we think a new military style "wristlet" band will enhance the watch even further if that is possible. We will add further images once a strap has been chosen and added to the watch!
