I really like the looks of this vintage Olma and it's selling for real cheap. Any glaring signs I should look out for? I know the crown is unsigned and probably not original. The hands look period, but maybe not original. I am not sure what kind of movement it is, other than the obvious 15 jewels. Thoughts appreciated. Thanks!

 

Nice "bullseye" style, likely early 1940s. The hour and minute hands look new relative to the rest of the watch, so I'd agree with you they are replacements. Signed crowns were generally adopted by many manufacturers in the early 1950s, so yours would likely have been unsigned when it left the factory. It looks similar to the ad below for your model:



You can use the ad above to hunt for replacement hands - looks like you get your choice of cathedral hands or plume hands.

 

Darn looks real nice of course that’s all I can say I don’t even know that maker, first Time I’ve seen it but nice dial

 

Thanks for your assessment and finding the vintage ad. Much appreciated! Yes. I do love the dial!

 

Like yours but older, it doesn't even have Incabloc ...
And unfortunately does not provide information about the manufacturer or any other detail:

Olma apparently used A Schild for at least some of their movements.

 

I would have guessed A. Schild, possibly Felsa.

 

AS 1130 (Wehrmachtswerk), I believe.

 

Nope.

 

Wrong bridge patterns.

 

Well, the AS 1130 was made with various bridge patterns, so I was trying to look past that. But you may be right.

 

@JimInOz @Rochete

Various other people also seem to think this movement is an AS 1130, but I understand that doesn't prove I'm correct since there is a lot of false information on the internet. Any thoughts when you look past the atypical bridge layout? It would be nice to see if there are numbers under the balance.

You may be right

 

Olma made a nice single crown compressor called Sea-Cup.

 

They also made a really cool double crown epsa compressor (Caravelle 200) which I was very lucky to stumble on..
Olma is in my opinion a nice brand that made some good quality watches back in time.

 

Sincere thanks to everyone and their due diligence helping me identify the watch and in particle the movement. Much appreciated!

 

That has pretty much anything you could hope to find in a SC. Great watch.

 

From Ranfft. It appears the AS 1130 had different bridge shapes.
"Remarks
so called Wehrmachtswerk (army movement)
option: Reed's regulator,
different bridge shapes,
sometimes separate escape wheel cock,
differently bevelled bridge and plate edges,
later samples with ring balance and/or mobile stud carrier, but even very late still without shock device (Fig.5, 6)
differences not known between 1130, 1142, 1149, 1243, 1286, 1295, 1304, 1339, 1383, 1387, 1392, 1399, 1401, 1420, 1487, 1502, 1522, 1540, 1542, 1548, 1573, 1597, 1667, 1685
two calibres of this line with 13.5''': 1337, 1511
two calibres of this line with 14''' : 1486, 1543
three calibres of this line with indirect sweep second: 1155, 1164, 1195
These were only produced a short time, since they were soon replaced by the AS 1188 with direct sweep second."
Interesting it came in 15,16,17, and 21 jewel movements.
