Lovely blued steel hands..... a very nice touch.
This is a issued Heuer stopwatch from the 1950's. I thought I had bougth a cool military issued Heuer, but some research of the GPO engravings on the back led me to the British Post service "General Post Office". Not as exciting as a war veteran, but still kind a cool.
The markings on the back says 6 GPO, BAU 53, 60107. 53 stand for 1953, the year it was issued. There is a website about GPO Watches, check out: http://www.britishtelephones.com/clocks/watches.htm My watch is number 6, described as:
"Watch No. 6 is an 8-hour, high-grade, keyless, lever stop-watch of the permanent-motion type with a continuously operating seconds hand at the bottom of the dial, and two stop-start centre seconds fly-back hands with an associated revolution register at the top of the dial. The centre-seconds hands make one complete revolution in 100 seconds over a scale marked in half-second divisions and the revolution register integrates the revolutions of the upper centre-seconds hand up to a period of 3000 seconds. i.e. 30 revolutions."
This Heuer split stopwatch, was issued for the accurate measurement and timing of the electro-mechanical call timing equipment.


The movement is a lovely finished Valjoux 57. Fully signed, and with a very loud ticking sound. The second hand at six, is constantly running, even if the stopwatch is not engaged.

The bridge and case is signed Ed.Heuer & Co, Switzerland.
The ref. 73633 is known in three different versions. The blue dialed 73633 B with white subdials. And the two different dials on the 73633 G, one all grey, and the other with black/dark grey subdials. The all grey is belived to be the earliest of the two.
This Monaco is in good orignal condition. Very nice dial and hands. The case has not been polished. The back is stamped with the Heuer logo and Tool No. 033, the special tool required to open the waterproof case.
It even have the original bracelet. That is a nice bonus. They are rare, and very expensive if you can find one.
The ref. 73633 G and B is listed in this 1972 Heuer catalogue.



The case back is plain with no Heuer logo. And is stamped 844 rather crudely. "ETANCHE ACIER - 20 ATM - AUTOMATIC" is also stamped around the edge.
The movement is Felsa FE 4611A and is signed G. Monnin France on the rotor. Later Swiss made Heuer divers have movements from ETA.
Inside of case back is signed G. Monnin France.

The case is the same as Autavia 1163, and is stamped 1163, not 1563 between the lugs at 12. This is normal, I have never seen a Autavia stamped 1563.





There is two versions, 7763 TH with tachymeter bezel, and 7763 MH, with Miles/Hour bezel. They was listed in the catalogues from 1968-1971. It's quite big at 40,5mm, lug size is 20mm.


In April 1912 Heuer was renamed “Heuer & co., Rose Watch co.” Charles-Auguste and Jules-Edouard at the urging of their American partner decided to use the trade name "ROSE WATCH COMPANY" on all watch movements imported into the USA. Due to high customs tariff on complete Swiss watches during this time period, Heuer would send a complete movement without a case. The movement was then installed in a US-made case.
In 1922, after ten years, Heuer stopped using the “Rose”-name. So from 1912-1922, all Heuer watches sold in USA was signed “Rose W. Co.”. A full range of pocket-, mens-, ladies watches and chronographs was marketed.
