This is what they call a "high-class" problem.

Loving this piece

Received from Intime today!!!

G-S Crystal cement comes to mind, or a silicone adhesive. The crystal cement from G-S has a nice applicator which could make the deal a lot easier. Silicone is tricky and messy to work with, but when it dries it can be removed fairly easily. To my knowledge, Rolex doesn't use glue when installing these crystals- they are a tight pressure fit.

if he really wants to sell it and have him get it serviced and you tell him you pay the service charge, if he's not willing to agree then don't do it. There are so many parts on this watch that can be replicated it could affect the price tremendously. Sent from my iPhone using Tapatalk

Same as yesterday!

I really like it my friend, is it a slate grey dial? Can you tell us more?

"I AM NOT 100% sure if it is authentic" is usually a good sign that you're dealing with a fake/rep

It's funny how quickly you can get drawn into these projects. At the start of this month, I had just finished my Space-Dweller, but was busy sorting out my other 1016 build (still incomplete). So it's not like I needed something else to take my time and money! But I was feeling insomniac that night, so I was off to browse the auctions for items on my long-term wish list. The second-generation Seamaster 300 has been on that list for some time. The Buy I found the auction for this SM300: With 20 hours to go, the price was still hovering around the $200 mark with just a handful of bidders. For a vintage SM300, that was unusual, but I could see why: It was obviously a fake. They used to call these cases Vietnamese, but I'm not so sure if that's still true. It looked to be the same kind that Yuki sells. The seller was local, so I asked if he could remove the US-only restriction on the auction. He said sure, but cautioned that there was some question about the watch's authenticity. So I responded: "I do not believe you have an original SM300. I am pretty sure that you have an aftermarket case, bezel, and dial, and I am willing to pay fairly on that basis." It turns out that this auction had caught the attention of the eager beavers at WUS-Omega, so maybe I should thank them for scaring the bidders away! I do believe that the seller honestly thought he had a genuine Omega. Based on his transaction history, he was more of a Rolex guy and when I spoke to him, he seemed mortified at the thought that he may be selling a fake. He sounded very relieved when I took the SM300 off his hands. I met up with his messenger at the shop of my watchsmith, who looked over the Cal.552 and pronounced it to be in good working condition. I paid in cash and took my prize. Here's how it looked when I first received it: Let's run down what's immediately wrong with it: Dial had "stubbies" (read: minute lines that extend past the hour markers), which are all too familiar to anyone who has researched an SM300 purchase. Sweep hand was too short and unpainted. Case was polished all around, not alternatingly brushed/polished. Bezel markings were colored like pickled radishes. (Koreans call them danmuji!) Also, the crown was absent because the stem had broken (disclosed). Post-Purchase Planning Considering how many buyers this sort of watch has fooled, I had assumed that this was a 1:1 case. My early plan, then, was to replace key bits with genuine parts. A white sweep hand was a must, and that day-glo bezel had to go! However, discussions with ChiMan12, ubiquitous, and pam153, quickly revealed that this wasn't going to be as straightforward as I'd thought. This "replacement case" is definitely NOT a 1:1 replication. The case may look like a spitting image, but the dimensions are significantly different in crucial areas like the crystal and bezel diameters. And by "significantly" I mean that you can't just trim a bit of plastic--the crystal's OD is off by 0.9mm. There was also no way to get a genuine bezel to fit without somehow adding metal to the outside of the rehaut. Bezel Headaches The bezel deserves special mention as it is dimensionally and functionally different from the gen. The rep turns counter-clockwise only, with 120 clicks. The gen is bidirectional with 60 clicks, ratcheted by three, sprung, ball bearings that are recessed into the case. The rep has two drilled holes, but only one of them contains a sprung roller bearing. They're really serious about cutting costs, aren't they? Gen without bezel is on the left, and the outline of the bezel teeth is clearly outlined on the case. And here's a mash-up of the back and front of gen and rep bezels, showing the difference in construction. Gen is on the upper half: Different dimensions, and different construction, so the bezel would have to stay. That depressed me, since I really, really hated the way it looked. It was an ugly color, and an instant tell, while replacing the insert was not a realistic option. I almost shelved this project, until I got the idea to artificially age the insert. I bought a few things from the hobby shop and started experimenting. In the end, the winning formula was unevenly applied Tamiya "Smoke" (to suggest tritium decay) buried under several layers of clearcoat. Some sanding to flatten the surface, some polishing so it wouldn't look as if it had just been sanded... done! My first-ever vintagizing job, and I'm happy with how it turned out. Sourcing a Dial The original dial wasn't bad, but those notorious stubbies were giving me fits. I remembered that DickBrowne had a spare SM300 cartel rep from Ubi, minus hands and a bezel. The dials on those reps looked pretty good, so I sent Richard (ahem) a PM. Speaking of "ridiculously generous", he sent the dial to me, free, even though he was hours away from going on a trip. You're a good man, Richard Browne! So I was a bit disappointed to find out just how big that dial was: Not even close, but I had an alternative -a much more expensive Plan B- lined up. If anyone reading needs a cartel SM300 dial, or knows someone who does, please shoot me a message and I will send it by registered mail. Own a piece of RWG history with an ex-ubiquitous dial! The Build Here are the genuine parts I used: Crown, stem, hands, gasket, 1171/1 bracelet with 633 endlinks, and... a NOS no-date dial: The case was refinished for the brushed/polished/satin look: The bracelet, as mentioned previously, is an 1171/1. It's not rare, and used examples aren't expensive. It is, however, a great-looking bracelet that's very comfortable to wear. The only negative is the clasp, which is incredibly tight and punishes my fingertips whenever I open it. Lately I've become used to wearing vintage Rolex Oysters, and I forget just how much better contemporary Omega bracelets were! The dimensions may be off, but the tall bezel and spindly lugs define the Seamaster 300: The legendary Cal.552, which I consider one of the most beautiful, mass-produced automatics ever made. On the caseback, note the pointed 'A' on 'WATERPROOF'--this is a tell! Also note the ill-fitting, too-thick rubber gasket. This is the fault of the case, which has too shallow a groove for the O-ring. If the caseback looks like it's protruding in the other pictures, that's because it is. On the pillow, and on the wrist. 633 endlinks are assigned to the SM300, but are not a perfect fit. I understand that this is also true for the gen. I do know that I had to sand the edges down to get it between the lugs of both this SM300 and my gen Speedmaster. I scratched up the insides of the Speedy's lugs pretty badly. Future Upgrades? A 20mm mesh bracelet would be a nice option, but I'm good ith the 1171 for now. Really, all that separates my PUSM300 from "NOS" status (like a Watchco) is a 166.0324 replacement case set. It's pricey, but it comes with a caseback, crystal, and the all-important bezel with lumed markers. If you haven't seen a NOS SM300 at night, believe me, it's a thing of beauty. But I can wait. I'm happy with how this watch turned out, and it seems to have scratched my SM300 itch. Now I just have to stay off eBay tonight...

civic: THAT is a stunning SM300 with a ton of character! Glad I could help in some way!

This is a great piece, and a very fitting nato strap.

Hey P, mine is a 1966 version by serial. Wish I had the skills and funds to part together a build but this one is a plain Jane gen. The NOS parts and cases are so expensive now it just makes sense to find a gen and do the homework for it. Mine has a replaced aftermarket plexi though so I'll have to get a NOS part of service part for that. Here next to the new one : Sent from the my iPhone using Tapatalk s

Buffed out the car this morning so combo pic. That is my 6263 on the hood. Sent from my droptop using telepathy.

The details on this thread and photos were great for finding the gen vs rep stuff. Excellent resource from LHOOQ Here's mine. Sent from my iPad using Tapatalk

Other options are NDT & MQ. Of the 2, NDT tends to be cheaper & more variable, MQ is probably the most expensive, but also the most accurate (most of the time). In either case, at this price level (high) I would recommend that YOU do your research (on gens) before clicking any buy buttons. No aftermarket part is perfect. They all contain flaws & YOU need to decide which flaws bother you the least.
