This one was used by a US Navy or Marine diver in SE Asia in the mid 1960's with personalized Olongapo SS bracelet.
Seamaster 300

 

OH, OH, me oh my......I gotta see movement pictures.

 

It's just had a service and should be gleaming. I need to take some macro pics of last week's acquisition too, so will see what I can do tomorrow!

 

Helvetia 82A fixed lug

 

Oh my god, here's one of mine top subjects, and such nice pieces shown here already!
Al, your Vertex WWW is awesome! I've never seen those with non SS case.
Here's my Timor, also from the "dirty dozen" I think they call it.

I also love the Favre Leuba. I have several CS(I) issued watches including this Omega:

...many others That I can post, gradually...
Cheers!

 

It probably had a back like this, but mine was backless when saved from a scrapper.

 

1950's Lemania Czech Pilot Watch + Cyma WWW
1938 Longines Czech Pilot Watch

 

I like your Timor WWW-very often these are seen with incorrect MOD replacement hands-many time with Vertex WWW hands

 

The hands on yours are correct

 

As a teaser, here's a lo-res pick of the movement, having just been reassembled and cased by Stefan after the service:

 

Great watches here.
My Lemania with red seconds hand(probably not original) says Hi!

 

Very, very nice.
My Omega RAF also unmarked and with a not so nice dial:

...and I think the correct reference is CK2292, not 2922, right?

 

Right you are! a bit of Omega dyslexia...Omelexia anyone??

 

What are the numbers on the case back of your Lemania? If they begin with a D red is correct IMO

 

Love those Czech pilot watches especially the Longines which is probably the only one of the 3 that can be traced back to WWII. Eterna and Lemania came pot war

 

So you mean during the War on Drugs?

 

RN300 ... '68

 

My CK2292 with HS8 marking :

 

Here's my Nite MX10, as issued to current UK SF. My usual beater, it's been a virtual daily wearer for the last 5 years or so (until my Speedy Pro arrives). I do have a CWC G10 that was issued to me when I joined the RAF a good few years ago - pics to follow when I find it.....

 

The number is 3660 and no D I'm afraid...
