Omega Seamaster DeVille Help

Hi all

Thanks in advance for your time on this. I saw an AUD $1500 Omega Seamaster DeVille which I'm very interested in and wanted to double check with you all that I haven't anything obvious. Are there any risk factors I should be aware of? It seems to be a valid reference in the Omega database. The following details were supplied by the seller.

Nice and clean movement. Works and runs properly, keeps time correct. Winds soft and smooth with long power reserve. No services done by the seller. Original crown. Original glass (Omega sign in the middle).

Cal. 562
Reference 166.020
Series. 22277937
Around 1965.
Around 34-35mm without crown.
Bracelet: 1502 (no.12).

Any advice you could provide would be greatly appreciated!

Thanks.

Nothing wrong except the price. They are gaining popularity but even with the BOR that's about 50% over for an unserviced example.
