Deployment Buckle for Longines Watch 18mm

Description

Quick answer: This is an aftermarket 18mm deployment buckle for Longines leather and rubber straps that taper to 18mm at the tail. It is made of stainless steel in a polished or brushed finish and replaces a standard pin buckle with a folding clasp.

Which watches does it fit?

It fits Longines straps that measure 18mm at the buckle end, which is common on dress and smaller sports models. What matters is the strap width at the tail, not the lug width at the case.

Why choose a deployment buckle

With a pin buckle, the strap is bent through the keeper every time you put the watch on. A deployment clasp keeps the strap at a set length and simply folds open and closed, which saves wear on leather straps. Stainless steel suits both leather and rubber straps and will not be affected by water or sweat.

How to fit it

1. Work on a soft cloth so the watch and buckle do not get scratched.
2. Remove the existing pin buckle from the strap tail with a spring bar tool.
3. Attach the deployment buckle to the 18mm strap end, following the fitting points on the buckle.
4. Close the clasp and check the fit on your wrist before wearing it. There is no need to remove the strap from the watch or open the case back.

Frequently asked questions

How do I know if I need 18mm?

Measure the width of your strap at its narrow end, where the buckle attaches, not at the case. If it measures 18mm, this buckle is the right size.

Does it work with rubber straps?

Yes. It is made for Longines leather and rubber straps that are 18mm at the buckle end.

What finishes are available?

The buckle is stainless steel in silver, with a polished or brushed finish.

Why switch from a pin buckle?

A deployment clasp saves wear on leather straps, because the strap is no longer bent through the keeper every day.
