Repair Tools

specialty tools and supplies for reliable repairs

We can recommend the following tools and supplies because we use them ourselves in the repairs of test indicators, dial bore gages, micrometers, calipers, etc.

You may very well ask yourself why do we show you these tools when we don't actually sell them? Consider it a reference page. You will probably find these items at retail watchmakers' supply stores. We've even included some part numbers which may make searching easier.

If you would rather have us handle your repairs, we are ready, fit, and able.

A good selection of tweezers should always be at hand. Genuine Swiss tweezers would be the preferred choice but here's a complete set at a fraction of the cost.

We use Dumont very fine and sharp tweezers for the smallest parts. Invaluable when dealing with hair springs, hands, pinions and those tiny Interapid dial screws. They're non-magnetic and made for watchmakers in Switzerland:

These Dumont tweezers are available in an assortment of other lengths and point thickness. It would not be a bad idea to have several on hand so that you can save the extra fine point tweezers for delicate work on the hair springs.


Bergeon Jeweler's Screw Driver Set

Quality repairs start with quality tools. We would not want to be without our Bergeon Jeweler's Screw Driver Set.

There's a screwdriver here for every screw you're likely to encounter, including those tiny Interapid dial screws.


Image

Better quality tools demand higher prices. We use quality Swiss punches to knock out the damaged bushings and then to accurately set the new ones.


Image

Hand Lifters: these are the Swiss-made hand lifters we've been using for the past 50 years. They will allow you to lift off any size hand. They work on a leverage principle. You simply press down on each of the two lifters and, if the front ends are properly placed under the collet, the hand comes off. If they're stubborn, a gentle "snap" will usually work.


Image

We couldn't possibly work without our eye loupes. Some of us prefer a simple 3X magnification while others us as much as 10X when dealing with tiny assemblies.


Image

Metal watchmaker's anvil (about 1-1/4" by 1-3/4") on which we do most of our critical work including the installation of hair springs on the gears and pinions. Various slots and holes on the upper surface (shown on the right) come in very handy for staking.


Image

The rawhide hammer is used to remove dents in bezels and to straighten and remove dings from metal dials. It gets regular use in our shop.


Image

Light weight watchmaker's hammer is used almost constantly. They are absolutely necessary when using the parallel punches to set bearings, for example.


Image

Naphtha is our cleaner and de-greaser of choice. It dries very quickly without any residue. Compressed air makes drying even faster (just a few seconds). We keep two bowls–full at hand. The one is reserved for a final "dip" after the parts have been thoroughly cleaned in the other bowl. This is helpful in removing the last bit of oil from hair springs and makes them work like new. Keep the bowls covered since Naphtha evaporates. Caution: Naphtha does not get along with some plastics but we have not found any issues with any of the plastics used by today's gage manufacturers.

Image

Very fine point tweezers are used for setting hairsprings. This is a less exensive option to the Swiss Dumont tweezers we use in our shop.


Image

The pin vise allows us work on center pinions when they need cleaning or straightening.


Image

To custom fit hands onto pinions and gears in dial indicators, test indicators and dial calipers, you will have to use a very small broach (reamer) to enlarge the pinion slightly for a tight fit that won't come loose.

  • miniature reamers are hard to find

Image

Synthetic Swiss watch oil is ideal for the bearings on test and dial indicators. This is what we use. Synthetic oil does not deteriorate over the years. It never gets gummy and does not have chemical reactions with metal or plastic parts. Use just the tiniest amount on your bearings and pinions. One vial will last for hundreds of repairs.


Image

Bergeon Swiss Made Fine Tip Oiler

Bergeon Swiss bearing oilers allow us to put very small amounts of synthetic watch oil onto the jeweled bearings, ball bearings and other hard to reach places. It is simply a fine pin which you dip into your oil vial to pick up a drop. You will not be wasting expensive oil and you will not be over-lubricating. Different oilers deliver different sized drops.


Image

The Craftsman (made in USA) screw drivers have served us well over the past 50 years. This collection, including the Philips (used for Mitutoyo repairs), will be more than sufficient.


Image

It is common practice to periodically run an indicator through a demagnetizer. Residual magnetism can cause a gage to stick at times, especially if the indicators are used around sources of magnetic fields (spinning metal, for instance). Place the indicator inside the opening, press the power button, and pull out slowly for about 8 inches. If your indicator contains magnetizable metal, you will feel a buzzing and resistance as you pull out.


Image

Instead of grease, when needed, we use this Anti-Seize compound. We use it regularly on micrometer and bore gage repairs and in certain instances, on indicators as well. One jar will last just about forever without drying out.
