Justasgood Posted December 1, 2008 Report Share Posted December 1, 2008 I ordered a Twin lock crown and tube for my vintage 5512. I have a 702 crown but gave up trying to find a tube. So I thought I would try to source a 700(original to the 5512/5513 of the early 60's) crown and tube to replace the modern 703 set. When I picked up the parts, my watchmaker handed me a tube and crown but the package of the tube reads 24-7000. ( the crown was loose and un packaged although new). Any idea what I have? Is this correct for the early 60's 5512/5513's? Thanks in advance, Kurt. Quote Link to comment Share on other sites More sharing options...
Mickey Padge Posted December 1, 2008 Report Share Posted December 1, 2008 Might be for a Rolex 6263 maybe? Quote Link to comment Share on other sites More sharing options...
JoJo35 Posted December 1, 2008 Report Share Posted December 1, 2008 Yes, 24-7000 is twin-lock Quote Link to comment Share on other sites More sharing options...
Justasgood Posted December 1, 2008 Author Report Share Posted December 1, 2008 So is the 24-700 coupled with the 24-7000 tube correct for a 1962 5512 Sub? Quote Link to comment Share on other sites More sharing options...
JoJo35 Posted December 1, 2008 Report Share Posted December 1, 2008 Yes, that is correct for that year sub Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted December 1, 2008 Report Share Posted December 1, 2008 Lucky score, K! Those are difficult to find at a decent price these days Quote Link to comment Share on other sites More sharing options...
Justasgood Posted December 1, 2008 Author Report Share Posted December 1, 2008 Lucky score, K! Those are difficult to find at a decent price these days Well I guess the question now becomes, should I install them? Or use the New 24-703 combo? BTW, I picked up another 24-702 crown....still no Tube Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted December 1, 2008 Report Share Posted December 1, 2008 Personally, I would not use the 24-700/7000 in a project watch. Rather, I would hold onto them for the time being as they are worth more NOS. Quote Link to comment Share on other sites More sharing options...

freddy333 Posted December 1, 2008 Report Share Posted December 1, 2008 I mostly agree with Ubi, assuming the project watch is ETA-powered. But if the watch is gen-powered (1520/1570), then I would certainly consider it. I have a couple that I plan to use on my gen-powered 5514 & 1665 when I do the next overhaul. If anyone is interested, moelarrycu has 1 for sale right now. Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted December 1, 2008 Report Share Posted December 1, 2008 But if the watch is gen-powered (1520/1570), then I would certainly consider it. Even for a gen caliber based frankenwatch, I would not use a NOS pair like what K has. If I had a used 24-7000 tube in good shape, I'd consider using that paired with a new 700 crown, but a tube NOS in the pack is simply worth too much to use for a franken.

I would only use it on my 5512....(remember the TZ post) However, I wear the snot out of it and if the value of the twin lock is as high as a couple $100, I would just as soon stick with the Triplock 24-703.

freddy333 Posted December 1, 2008 Report Share Posted December 1, 2008 I hate to say this, but I think you may have a brand new aftermarket Twinlock. The gen should have striations around the bottom edge of the crown as you see here Here is the top Quote Link to comment Share on other sites More sharing options...
Justasgood Posted December 2, 2008 Author Report Share Posted December 2, 2008 Hmmm, I never noticed that. Interesting. I guess I'll discuss this with my watchmaker in the morning. Thanks. Quote Link to comment Share on other sites More sharing options...

The gen should have striations around the bottom edge of the crown as you see here Crown looks okay to me. These old crowns had a top layer of thick foil wrapping the actual crown. Those are the striations that you see- The foil where it is pressed and 'sealed' to the crown. Underneath is a solid SS crown complete with the coronet, etc. I know this to be 100% the case as I had coaxed ziggy into unwrapping one of his some time back a few years ago, mostly to see what was underneath. Thankfully, 24-700 crowns are easier to find than the tubes. Quote Link to comment Share on other sites More sharing options...

Thankfully, 24-700 crowns are easier to find than the tubes. It is definately a foil wrap and I also have seen a TZ member unwrap a few for the heck of it. I feel comfortable in my watchmaker's assesment but I will entertain all expert opinion. Quote Link to comment Share on other sites More sharing options...
