Hello all, I am doing some research on Elgin British Deck watches used by the Royal Navy during WW2. I have owned two examples, but only one in my possession at this time. Doing a small amount of research on the serial number for dating purposes I get the usual information: Elgin Grade 581 22 jewels (some marked 21 jewels but actually 22) B.W. Raymond Movements All Adjusted to 5 Positions 20,800 total made 9 Runs by Elgin totaling to the 20,800 between 1941 and 1943 Looking at my serial number (41757691) and the run it was included in it looks like it was produced in the eighth run of the 581 Grade in 1943. Looking at my first example and its serial number, it also was included in that run. Here is the run information that I can gather about the runs and serial numbers. 1941, 39261001 to 39261500, 500 units 1941, 39516001 to 39516300, 300 units 1942, 40470001 to 40471000, 1000 units 1942, 40500001 to 40501000, 1000 units 1942, 40999001 to 41000000, 1000 units 1942, 40294001 to 40296000, 2000 units 1943, 41165001 to 41168000, 3000 units 1943, 41750001 to 41760000, 10000 units 1943, 42077001 to 42079000, 2000 units So, I started searching for all the Elgin HS3 Royal Navy examples that I could find on the internet and jotted down their serial numbers. After only 10 minutes of searching I found the following 10 examples: 41751157 41751750 41753425 41753480 41753706 41754653 41755700 41757066 41759061 41759426 Now quickly looking at the serial numbers it shows that ALL the examples came from the same run. That run was supposedly completed with 10,000 pieces. The serial numbers show HS3 examples running from the first serial number range to the end of the 10,000 (1,157 to 9,426) This CAN NOT mean that there were 10,000 Elgin Grade 581 22 jewel watches that went to the Royal Navy, or can it? There has never been a definitive answer to the actual number of Elgin HS3 Deck watches there were produced, I've been looking for years. I would like to get a step closer to that here! I am hoping for anyone who may have an Elgin HS3 Deck Watch or British issued example in this serial number range (41750001 to 41760000) to post the information. This also includes serial numbers in this range that ARE NOT British military issue. This would give up great information either way. I understand that online information sources that give serial numbers, date of manufacture and run quantities aren't always accurate. I am going on what I have found to be available. If anyone has further detailed information regarding this watch, date of manufacture, run quantity and number of examples that went to the British Government please post. If this topic has already been covered and answered can someone please forward me the thread? Thank you all.
