Overseas Strap Change Tutorial

Robert/respo had a great idea a few posts ago regarding the need for a pictoral on swapping the OS rubber and leather straps.  As one who doesn't have the patience to head to the watchmaker to have a case back or watch strap removed, I've done this operation a few times and feel it can be safely tackled by the average owner with STEADY hands.  So here's the drill....

Find a comfortable spot with good lighting.  Put your reading glasses on if you got 'em.  Spread a soft cloth down to organize your bits and keep any tiny screws you drop from bouncing to kingdom come.  Assemble your tools.

I prefer to begin by removing the deployment buckle.  A nice touch with the OS design is the set-screw that holds the buckle firmly to the strap.  A proper-sized screwdrive can be inserted through a cut-out in the deployment to unfasten this screw.

Having released the opening or long side of the strap, we address the short side.  This end has a single set-screw which secures the pin that attaches the deployment to the strap.  The very small screw must be removed (a loupe may help position your screwdriver securely).

The pin can then be pushed through, completely separating the buckle from the watch.

Now we head over to the lugs.  The design carries over the the first generation OS because it works well.  A short screw must be removed from each side to access the pin that actually holds the strap to the case.  Once the screws are removed, you push the pin out with the proper tool (a narrow screwdriver will do the trick but be gentle around the lugs as the polished surface is unforgiving).

Here we are in a complete state of undress.  To reverse the process, a bit of Loctite 242 or similar "threadlocker" adhesive is STRONGLY advised.  Its easy to use and any excess wipes away with a tissue.  Keep in mind that when you go to release the screws next time, you must first break the adhesion with a firm twist.  Hence the need for a properly sized screwdriver to prevent damage to the screw head or surrounding case.  A blue residue will remain on the threads, which is a good reminder to use the Loctite again...

And voilà, we are done!  I don't use adhesive on the large screw that secures the buckle to the long strap - just don't feel its necessary.  But that little screw on the short end definately needs some.  Now is the time to enjoy a little refreshment angel.

Thanks for that Dean - I'll slot the link to this thread in my bookmarks. My Dual Time is still on the rubber strap it came with and not sure if I'll even bother changing it .  If I do though , I'll refer back to this. Cheers Brent
You are my hero, Dean!

This is a great tutorial.  Just what I had imagined and hoped for.  Thanks for taking the time to put this together for us.  It is a great service for our THL community. I am so glad you held off on the wine until after all the little tiny screws were in place.  wink Here's my photo, but judging from the lack of focus, it is entirely possible that I begin with the wine rather than finishing with it.  Thanks again for posting the tutorial, Dean. Kind regards, Robert

My pleasure Robert, now we just need

That's an old photo

...and my AD was doing the strap change.  Never fear, except for the Loctite, I am now well equipped:
Dean,

I wonder if you would explain why you wear a glove(s) to do this work. I will post my experience in changing the croc strap for a bracelet on the OS Chrono US Edition soon. There is more than one way to skin a cat as they say; and there are a few aspects of your approach that differ from mine. :-) Joseph
Just because ;-)

Actually the glove was to eliminate the distraction of a hand in the pictures.  I look forward to your approach and the ensuing controversy surprise
Well done, Dean! BTW, have I missed your introductory post on your new

I don't have anything to add to the exellent coverage the OS has already received from the Loungers.  OTOH, stuff like this is too much fun to resist, and I hope to have some interesting shots "in the wild" to share later yes.

Thanks Dean.. The Loctite 242 tip is appreciated. Now, I have a Deployant on my Lange, but want to change it to the tang. Any help with that in a pm gratefully received from anyone! Gary

Hi Gary, It's a much trickier job and requires a special tool with a tiny "U" shaped head to engage the pins holding the buckles in place. It does require some pracice and there is a risk of scratchig the lugs since the gold or PT is much softer than steel. I'll try to take some photos separately of the technique since i have several Langes and have changed tangs to deployants and vice-versa many times. You can PM too for specific questions. Regards, Joseph
