Some Military Horology!

From time to time (heh) on this blog I digress into different subjects unrelated (or only tangentially related) to wargaming. One of my many non-wargaming hobbies is horology... the study (or in my case, collecting) of watches. Combining this interest with another of my interests obsessions, military history, makes for an fascinating intersection.

This is a lovely piece isn't it! It's a Heuer "Bundeswehr" 1550 SG flyback chronograph. These were issued to the Bundeswehr (German Armed Forces) in the Cold War - particularly in the 1960s and 70s.

The case is stainless steel of course, you can see the four fixing screws right next to the lugs. The Bundeswehr item number is stamped on the caseback, note that this isn't the serial number... that is stamped on the side of the case between the lugs.

On the other side of the case is the manufacturer's model designation - 1550 SG.

The watch came from the seller on a very nice grey leather strap but I immediately ordered an NOS Bundeswehr strap from Jurgen's in Germany.

The strap design is now commonly known as "Bundeswehr" due to its association with this watch. It's a three-piece leather item - a two-piece buckled 20mm strap attaching to the watch between the lugs as usual, and the third piece being a flat oval leather pad fitting underneath the watch case. Supposedly this is due to the watch being used by pilots in the Bundesluftwaffe (air force) where the temperatures in the cockpit could vary from freezing to very hot, and the leather pad was supposed to insulate the pilot's wrist from the hot or cold stainless caseback.

  

Accession number stamped on the strap as well.

Here's a better view of the full strap.

I really like the dial design of this watch. The bezel rotates of course, to keep track of elapsed time. The subdial at the left runs the seconds, the subdial at right keeps track of chrono elapsed time up to 30 minutes, and the chronograph second hand (seen at one o'clock here) is started and stopped by the top pusher, while the bottom pusher resets the chrono second hand from being stopped. HOWEVER... if you push the bottom button while the chronograph is running, the chrono second hand flies back to 12 and restarts automatically. Hence "flyback".

The "3H" in circle is typical of the Bundeswehr issued watches, it signifies that the markers and hands are coated in tritium, which glows in the dark ("3H" is the chemical symbol for tritium, 3 is the mass number and H is for hydrogen of course). Just so there's no mistaking this there is also a tiny "T" over the 6.

Of course there's prominent "Heuer" branding here as this watch predates the 1985 acquisition of the company by the TAG Group, the watches thereafter being branded TAG Heuer.

The Bundeswehr strap makes the watch wear even larger than it is and my wrist isn't huge, so I've been wearing the watch on a one-piece nylon NATO strap.

I was really happy to pick up this watch as I've wanted a Heuer Bundeswehr flyback chrono for years, it was one of my grail watches. They're not that rare but there is a really weird variation of the piece called the "Sternzeit Reguliert" (regulated star-time) that was used by the artillery and was set to "sidereal time" (based on earth's motion relative to distant stars rather than the Sun). A sidereal day is 23 hours, 56 minutes and 4.1 seconds. Try that as your excuse next time you're a few minutes late for a meeting ;-)

I find this stuff fascinating, but if you want a deep dive into the Heuer Bundeswehr watch you can have a look at this site.

Next up is the watch I wear when doing Great War living history. It's a "Queen Anne" hand-winder from West End Watch Company. This is also a fully original piece.

The strap is great, it's from vintagewatchstraps.com and this guy is a real artisan. I sprung for the hallmarked sterling silver buckle and it is just lovely.

Some honest wear on the dial here but the watch winds well and keeps reasonable time at events. The Great War was the real origin of the men's wristwatch and the start of a fashion that survives to this day. Strangely enough, for a time after the war, some veterans resented civilian non-veterans wearing wristwatches - stolen valour! Pretty wild stuff.

Moving forward about 25 years, here's a Swiss watch issued to the German army in the Second World War. The Germans made use of a lot of Swiss watches for their armed forces, including this example by ARSA (A. Reymond SA). It's a handwinder too, as all of these watches are, and is marked "Watertight", "Shock-resistant", and "Anti-magnetic" on the face. All of these properties are important in a military watch, as magnetic fields can affect the running of the watch.

What marks this watch as military issue is the stamp on the case - "DH" stands for Deutsches Heer, the German army. The serial number is stamped between the letters.

Here's a pocket watch from the same maker. My wife got this for me as a wedding present. 

Also "DH" marked, naturally. Nice watch but not many people wear pocket watches anymore do they!
 

Lastly here's a cool RCAF (Royal Canadian Air Force) service watch by Waltham. Like the ARSA wristwatch it's pretty petit by today's standards but it's in very nice condition with what I believe is an original nylon strap.

Military accession number on this one as well (I think the /42 indicates wartime issue) but it's the paperwork that came with it that's really remarkable...

Check this out, original Air Force paperwork! "Requires overhaul"

Here's the evidence it was overhauled... in 1965! Who says the military is wasteful... this watch may have been in service for over 20 years.

Tested and accurate to within 30sec/day... it's no quartz watch or iPhone but not bad for an old hand-winder - keep in mind that the "COSC standard" for accuracy of mechanical watches established by the Controle Officielle Suisse des Chronometres is -4s/+6s per day. I only have one chronometer in my collection (a Tissot Janeiro chronograph) so I'm not super-fussed. These watches are of interest for their intricate mechanical function and aesthetic appeal, not their super-accurate timekeeping.  

Anyway I hope you enjoyed this digression and if you are worried about spending money on awesome watches, you should really stay far away from chrono24.ca!
