Watch for Sale: Excellent Condition Vintage Seamaster, Omega Cal. 552 in Explorer Look with new NOS Dial and great Luminousity
Sold out, sorry!

Why I think this watch is interesting:

This was going to be my Omega Vintage Seamaster Keeper. But I just think that the hot and humid climate here in Bangkok is the ideal home for this watch. And I am almost never wearing watches on a strap. Thus I have quite some pain separating from this really beautiful watch. The dial must have been refurbished, otherwise I could not explain that luminosity. But it was certainly done by an expert, look at the pictures and close-ups below.  The dial is immaculate and beautiful, but in my opinion, the real beauty of this watch is inside: the historic caliber 551 (please read below).
The watch is running +/- 0 seconds! Yes, spot on. Because one customer wanted me to tune the watch as accurately as possible.

I still think this is a great Omega, especially since the Cal. 552 is very similar to the the first historical C.O.S.C caliber (551) exclusively certified for the Constellation Market introduction in 1959. The only difference is, that Omega sent the 551 to the "Observatoire" in Neuchatel, while the 552 was not officially certified. But from my regulating experience I can tell that this is a great movement. Without a timing machine and within a very short time, I had the watch regulated (dial-up) to +/- 0! That swan neck regulator is a joy to work with.

The Movement, Cal. 552

The serial number of 22'xxx'xxx dates the year of production of this Omega around 1965 (source: Cooksey Shugart's Complete Price Guide to Watches 2001). And between 1966 and 1968 according to another Omega source (Kreuzer, see below). The caliber 552 is very similar to the caliber 551 introduced in 1959. The main difference is, that the 551 holds an exclusive C.O.S.C for the Constellation market introduction. Like the 551, the 552 features a beautiful swan neck regulator, 24 jewels, great bi-directional winding, plain glucydur balance, 19'800 bph, first flexible spring block for easier regulation, power reserve over 50 hours due to a main spring with 7 evolutions (source: Omega Designs by Anton Kreuzer)

Watch Description and Condition
: Case, crystal and movement are in excellent condition. Dial is very professionally refurbished and has a great luminosity. On this picture, you can see a slight crack in the inner bezel, not very noticeable but still I want to mention this so you know what you are buying. The slight crack is at minute marker 14 on the inner bezel and a sign of age, these kind of small cosmetic errors are often found on watches that are almost 40 years old.

Since I had to remove the movement for this task, I took the chance to show the beauty of it on a movement holder


I include this very practical traveler pouch from WESTERN UNION/Bank of Ayudhya with interesting Thai Language writing instead of yet another watch box to be stored away


The beauty on my wrist. Thanks to the very small outer bezel the watch looks a lot bigger then the 34.5 mm would suggest. It really hurts to let this one go, but at least I have those pictures as memories
