Overseas Strap Changing Procedure

Discussions on swapping the Overseas straps and bracelets around led me to create this little photo essay describing the process. Its easily accomplished without resorting to a watchmaker   Begin with  a comfortable spot, good lighting, and your reading glasses on. Put 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 start with the deployant buckle. The OS design features a set-screw that holds the buckle firmly to the strap. A proper-sized screwdriver can be inserted through a cut-out in the deployant 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 a pin that attaches the deployant to the strap. The very small screw must be removed - be careful not to misplace it.

Once this screw is removed, the pin can then be pushed through to separate the buckle from the watch.

Now we head over to the lugs. 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 but be gentle around the lugs as the polished surface is unforgiving.

To reverse the process, a bit of Loctite 242 or similar low or medium-strength "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.  Notice a bit of tape on the table for easy clean-up.

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.  Enjoy the "new" look of your old watch
