E-bay LeCoultre...What a mess. (Lug hole repair)


Recommended Posts

After wanting one of these Bradley II watches for a long time, I jumped on this one and paid way too much. At 1st it looked nice.

Seller says "recently serviced". I measured amplitude DU & DD and it came out to about 190. PD & PL are 170, beat error 11 & running anywhere from +300 to -250 seconds.

Then I went to remove the strap....

Fortunately I have a very good bench jeweler nearby with a laser welder. He says he can fill them but drilling the new holes is up to me.

Now what?...Anybody have experience drilling straight holes at an angle?

  • SuspectDevice changed the title to E-bay LeCoultre...What a mess. (Lug hole repair)

somewhere ive seen a cool right angled drill , that may work, alternatively you go straight through from the outside of the lug all the way through to the inside of the other one and back out. then you fill in the outsides of each lug and polish.

I'm always curious when I see a recently serviced watch on eBay. sometimes I've even seen the timing machine results pictures on eBay and are not always really good? Your amplitudes by the way or way too low and I'm curious about how you measured your beat error? This is because the witschi timing machines and the Chinese machines the maximum beat error is 9.9 ms. 11 is basically an unheard-of number its way too extreme.

That brings up another question I have.

What are curved spring bars used for?

Curved spring bars are a style thing that allow a strap to conform more closely with the curve of the case. It can result in a very clean look to the watch in my opinion.

Some watches are designed to only use curved spring bars, and this appears to have been the original situation with yours. Someone's then come along and drilled the new holes to accommodate straight spring bars.

With regard to straps, I've been experimenting with using ordinary straps together with curved bars and so far they've worked, but I've also seen straps specially made with a curve to accommodate the bars more precisely.

Here's an example of a Bremont with curved spring bars (taken from Chrono24):

The spring bar's  falnge is clearly scratching on the lug. I would try a curved simple( flangeless) spring bar. 

Beautiful watch, wear it in good health.

I picked up the repaired case from the jeweler today. They did a great job laser welding the holes.

I'm waiting on a slow boat from China to  deliver the drill bits I need to continue.

In the meantime I found some shoulder less spring bars and used the 2 spoons trick to bend them into shape.

The price for the repair was $300 & done by Joden jewelers of Grove City, Pa.. In case anyone needs the same type of repair, I recommend talking to Steve who is the bench jeweler there.

I actually have a spring-bar bending tool.  Never used it, but I am just a hobbyist, so not that many opportunities arise.

Bergeon 5973? I have one and I managed to snap a load of spring bars in half... I bet the 2 spoons method is better!

LeCoultre update....

I had to buy a whole coffee can of spring bars from a watch maker's estate to find a few that would work. When the add said "assorted", they were not kidding. 😆 Anyway...This was the result.thumbnailgdbrbwr.thumb.jpg.a544db75f2920e2fb833c5f0a2ac22d8.jpg

Next up was making a drill that would work around the lugs. I decided on this and it worked pretty well with an extra long 0.8mm bit. I used a Dremmel tool, pointed tungsten bit to mark/center punch the holes.

The end result. Sort of...

Next order of business is to clean & oil it.

Nice job!

Did you get the drill bit with the offset curve from China or did you custom make it yourself? How long did it take you to drill the hole?

 I used 3mm square brass bar and curved it using heat. Then I drilled two 1/16" holes and slid the long drill bit through both. After that I super glued the bit into the holes and cut out the middle part with a Dremel tool.

The 1st hole took about 10 min & the other three were about half that time each. I'm not sure I'd want to try and drill anything hard using this procedure. 14K gold was quite soft.

 I really like these unusual art deco cases that were popular back in the 40's-50's.

They aren't in style anymore so they can be purchased inexpensively.

Personally I would treat any eBay watch in which the seller states that it has been "recently serviced" with a mountain of salt!

I've now purchased 3 e-bay watches that said they were serviced recently. I could easily tell they weren't. The barrel spring was the biggest giveaway. It looks like one person put a drop of some kind of oil on each one of the pivots to make it look like they did something. (the dial side was dry)

Anyway...I just got a e-bay 480 LeCoultre movement that looks nice to work on. In all 4 of the above watches, I've purchased an extra movement to actually restore. I put the original one in a little snap case to protect it in case I mess up. So far so good, This will be my 10th clean & oil and I haven't destroyed anything other than a cannon pinion (wrong tools) & I did loose a spring on my 1st rebuild (bad technique).

The 480 looks like this.

Look how exposed the escape wheel is. This looks like it will be easy to oil the pallet stones for once.

Also...I use the TimeGrapher cell phone App which goes up to 11 ms.

I know it's not the best but my primary concern is to get the watches cleaned & oiled so I can wear them without damage to the movement from running dry.

    • I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward?
    • That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much. 
    • Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release. 
    • Yes, "Sold out" is difficult to understand. There doesn't seem to be a lot going on. It's been nine months since any new video was published on the Watch Repair Channel. The Level 4 course on watchfix.com has been in progress for what feels like forever (several years!?). Maybe Mark's enterprises aren't doing well or perhaps already so profitable there's nothing much to motivate him for more material. Or, perhaps these days he's more into crochet. The real reason is probably something entirely different but it would be nice/interesting to know. I don't mean to sound gloomy or pessimistic, but I wouldn't be surprised to be met by an HTTP 404. Every day feels like a gift. Speaking of watchfix.com I've been postponing the "Level 5: Servicing Chronograph Watches" course for a very, very long time. Anyway, I just enrolled on it so it's going to be very interesting to see the videos. I must say, IMO there's nothing really that can compete with Mark's courses when it comes to presentation and video quality. It's simply world-class and makes me associate with some really expensive BBC productions.
    • Steel has some funny properties, or at least counterintuitive. The modulus of elasticity is effectively (not exactly, but close enough) the same for steel that is annealed and hardened. What changes is the point of plastic deformation* . If the movement of your spring doesn't pass that, it should work fine. It looks a little thick, I would thin it a bit maybe from the main body out about halfway, maybe 10-20% thinner (not in thickness, along its form). But if it works it works!   *So- if you have two bars of the same steel, one annealed, one at 600 Vickers (general hardness watch arbors might be), clamp them to a table so the same length is hanging out, and put a weight on the ends, they will bend the same amount. But if you continue to add weight, then remove it, at a point the annealed bar won't return to its original straightness. That's the point of plastic deformation. But up to that point, as springs, they are the same. However- their wear characteristics will be very very different. And getting the hardened bar past its point of plastic deformation takes a lot more effort.
