Notes

Screw for dial: under some conditions these little screws have an annoying habit of unscrewing themselves as a result of vibrations. Don't take it personally if this happens to you. We suggest you tighten the screws on a regular basis—perhaps each time you calibrate the indicator—so that they won't fall out and jam up the works. It's a little bit like tightening those screws on your eyeglass frames, before they fall out—probably while you're on vacation somewhere.

Hair springs can be daunting so we've made a hair spring and gear assembly available. Just remove the old gear and hair spring, and replace with the new. See the parts list above.

Crystal replacement: the bezel is threaded and unscrews. Hold the lower bezel plate steady with a small screw driver or pin, placed in one of the two holes, while you unscrew the bezel. The crystals are flat and must be inserted with a crystal press.

Stem attachment: If the mounting stem is bent or broken you can replace it with a bit of care. When you remove the old stem, don't lose the other parts. Unscrew A (#18), remove B (#19), tap out the bushing E (#22), save the washer D (#21) which goes on the inside, then remove stem C (#20). Reassemble in reverse order.

How to tighten a loose bezel

The bezel is screwed on as you have probably noticed.

Take a look under the rim and you'll see two holes. Insert a rod, a pin, a screw driver, something small into one of the holes. This will keep the plate from rotating while you turn the bezel and now you can tighten it again, by hand.

If you have the small diameter bezel, there won't be any holes but there will be two slots (you can also see this slot in the enclosed photo). The slots serve the same purpose for the small diameter indicators (but not for the large diameter).
