The Breitling Watch Source Forums

we have all seen these - and in the end I just couldn't resist to pick one up in very decent condition.

The second authentic Breitling/Wakmann co-branding example we know about, the only documented Military Breitling watch for the US and (for me) surprisingly late for a "pocket watch" in military use ?

The original MIL specification is from 1943 (Hamilton supplied these), adapted as MIL-W-5605 in 1950; Breitling's model reference is 605-A; the MIL specs were again adapted in 1957. I assume the "AN" part marking makes my watch one used by the US Navy ?

for those interested in the contracts specs, details here: http://www.mwrforum.net/forums/showthre ... tion-watch

tried to google the contract number to find out a bit more about time frame and quantities, but no luck.

Beautiful dial and a "black-on-black" engraved script Breitling logo, caseback marked both "Breitlingwatchcorp Swiss" and "Breitling Swiss Made", serial number dates it to 1961; movement is a 19 lignes Valjoux R5 KVM.

Nice watch!

While "AN" is usually associated with aircraft fasteners, it probably has the same meaning in this case.
AN - It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army and Navy, hence AN.

thanks for the "AN" clarification !

Lovely!

No matter what date is reflected on the outside of the case back with the contract number, you always go by the serial number inside the back to date these with the op's being 1961. I see them incorrectly dated all the time in ads. This one was later with a 1971 serial number. They made a ton of them.
