Bestest and Tesatast test indicator
spare parts list These parts are for all recent model Bestest indicators ending in -3 or -5. The only difference between the two is the color of the dials, spacing ring and the hand. We do not have parts for the older models ending in -1 or -2. Tesatast indicators use the same parts with the exception of the dial. Repairs: if you'd rather have us take a look at your indicators please see page 30.

Putting a new hair spring in place can be quite a challenge, so we've made it easy for you by offering a completed assembly which includes parts #4, #7 and #8. All you have to do is screw it back onto the indicator. Make sure you select the correct horizontal or vertical style assembly (see item #8 above).
The old crystals are removed with a special tool which acts like a suction cup. You can improvise other methods but you're likely to cause damage. Often times the new crystal, which is slightly convex, can be snapped in by hand, but even here, we use special equipment to avoid damage to the indicator. It's best to leave this to someone with the right tools. |
