First Time Owner of an Omega, My 166.010 & Questions on Beads Of Rice/BOR Options...

Hey Y'all,

I've always been interested in vintage watches and especially omegas, currently have a good lot of 70s-90s Seikos I've gotten from my dad and my late grandfather. I was always amazed at how such small movements can last for so long! My dream watch is a 70-80s Omega Speedmaster Professional (super unique... haha)

After casually looking for the better part of half a year I stumbled across this watch on Chrono24 listed for $489 and I decided with that deal I was crazy not to go for it. Its a 1966 Omega 166.010 serial no. 23031249 I believe it is an earlier production '66 due to the earlier style crown and second hand along with the serial number lining up with that, although not 100% sure when they stopped those and changed to the newer style. Rotor is correct and the rest of the movement looked good and lined up with the slightly earlier production 166.010 with a 562 as it was before they updated to the 565 with quickset and everything.

Here's a photo of the Movement: (sorry if it doesn't insert right I haven't posted too much here)

Dial is honestly in spectacular shape, has slight bubbling but it's pretty much impossible to see with the naked eye, it's a silver sunburst dial that has patinated to slightly more champagne. It has the Onyx hour markers, I figured they'd be a little bit better for daily use rather than tritium they also contrast with the dial beautifully. Looks to be original text as well, looks very uniform and the script is correct. T in Seamaster is also dashed correctly along with he correct shape for a mid production S in Seamaster.

Here's a couple photos from the listing as my camera isnt great...



Dial looks good and those photos should hopefully showcase that. Also has an omega signed crystal with magnifier! I know its not original but I definitely prefer it.

The case I would say is in alright condition, it has been polished before as y'all can probably see with the slight rounding on the lugs, and has a small dent on the top but I wouldn't say its been too abused. The previous watchmaker was not terrible and the polished vs brushed areas is correct so I think overall they did a pretty fair job. Interesting to note, I don't believe the case back has been polished, or if it was, it wasn't very strong.


The watch has no known service history, although according to the timegrapher it doesn't seem like its too bad, amplitude is pretty solid, no beat error but is running about 20-25 seconds fast although in my experience it only seems to gain about 7 seconds a day. Will definitely need a service soon, probably when the accuracy gets any worse.



Overall Its been a great watch! definitely more excited to wear it as time goes on.



Although one question I do have is about BOR bracelets, from what I've seen these watches could come with leather or the BOR that was sold by the dealer where they picked the one with end links that works best. From what I've seen it takes No. 11 Endlinks but do any other ones work? I've seen a lot of No. 70s along with does anyone know the proper reference for the bracelet? I've seen a lot of fake/aftermarket ones available on eBay and ive been thinking about getting one of those for the meantime as $200-300 is nearly more than half what I paid for the watch, and I figured something new would probably work a little better for every day use. Are these highly advised against? id figure for $80 they cant be that bad... if anyone had any advice on that or where to find proper BOR ones or aftermarket ones that would be awesome.

Thanks for reading,
Max

Nice find. Welcome to the forum.

Yes, you need a 5-row BOR (1502, 1036 etc) on 11 or 511 end links. Original vintage BOR are around 200-250$ with end links, but think that you can use them across various watches. I would vote to go for that.

Various people sell some in the parts section and quite often.

My sister reference on the bracelet:

As @theluckyluke noted, a 5-row BoR with #11/#511 is correct for this reference. #12 end links would probably work fine also. Usually it's a bit more economical to buy a watch that already has the bracelet. Adding one after the fact will cost you that $200-$250 extra. Or buy a watch with a bracelet and sell that one.

Agree with the comments above. 70/570 Endlinks are not correct for this reference. They’re primarily for Seamaster Devilles. You need a 5 row BoR with 11/511 Endlinks.

Also, your crystal isn’t necessarily a replacement. omega did offer crystals with date magnifiers in the 60’s. It’s could well be original.

Awesome I’ll keep an eye out then! I figured for $490 I probably couldn’t find a watch in better condition with a bracelet for under $700 so I decided to just go for it. Thanks for the response!

Ohhh okay good to know! Is 5 row the number of beads that are polished?

Hmm I was thinking that it could’ve been original and I had read it somewhere I just didn’t remember where…

Yes, generally speaking, there’s two types of beads of rice; 5 row and 7 row. The 5 row is correct for 166.010’s

Awesome! Would the one you have for sale be similar?

Also where would you guys recommend getting it serviced? I’m considering sending it to omega as I haven’t heard of any horror stories from them! I’m in the Charlotte area too if anyone knows good watchmakers around here 😀

Maybe you couldn't, it depends where you were hunting.

Nope, wouldn't recommend Omega. Search the forum for recommended independent watchmakers.

Haha yea I suppose if I was going in a couple diffrent places I could find lower but I wanted to stay sorta main stream and have some buyer protection so I figured chrono24 was pretty solid!

Hmm alright I’ll have a look around then thank you!

I have never bought anything from C24, usually horribly overpriced and the private sellers aren't particularly trustworthy. Glad it worked out for you.

Yea me neither it was my first one! I had seen lots of overpriced things on C24 and I felt the private seller seemed like a nice guy who was just selling a watch. I am too!
