Service + Repair: Omega Speedmaster Telestop 145.037 calibre 861

IMG_7947Linas from Belgium send me this Speedmaster, and, on first inspection, my heart did sink a bit.

The hands are either wrong or missing, the crystal and tachymetre ring aren’t original, and the watch isn’t working.

But the 145.037 is a very rare watch, and it will be worth putting in the extra effort to find parts and get this watch going again.



The sub hands and the central second hand aren’t original, and the hour and minute hands should be white.IMG_7951

The motley collection of hands.IMG_7952

The movement doesn’t look too bad.IMG_7953

The pusher gaskets have dissolved completely.


The pushers have large thread at the bottom, and the only explanation that I can come up with is that you could attach cables to them to remotely operate them. This could be used for test rigs where you have to time the length of events. The cables would look a bit like the ones used in the olden days for remotely operating camera shutters.IMG_7956

The tachymetre ring isn’t original, and somebody used all sorts of O-rings and a piece of cable to bodge the ring and crystal in.IMG_7957

Time to take the movement apart.IMG_7959

A bit of rust, but not too bad.IMG_7970

The chronograph is off, and I now can start on the base movement.IMG_7974

A bit of dirt on the crown wheel, but nothing too bad.IMG_7976

The gear train.IMG_7979

On the bottom plate, the fourth wheel arbor that drives the sub second hand is bent, and I will reshape that later.IMG_8015

This is what the crystal should look like – the tachymetre scale is printed onto the back side of the crystal. On the right, the new crystal gasket. Now I’m only waiting for the inner bezel ring, which is on back order.IMG_9291

The obligatory new mainspring.IMG_9292

I start off putting the base movement back together. The balance jewels are now in, and so is the plate that holds the lower barrel arbor.IMG_9293

Now I can put the gear train in. I have straightened the fourth wheel arbor.IMG_9294

The keyless works, which will enable me to wind the movement for testing.IMG_9298

The base movement is in, and I wind it up.IMG_9300

Now I can put the rest back together.IMG_9301

The bottom plate complete.IMG_9303

I clean, sand and re-paint the hands in white.IMG_9320

The new sub dial hands are a bit too small, and need broaching.IMG_9321

All hands back on, and looking so much better!IMG_9323

Now I can case the movement.IMG_9325

The watch looks great again, and, above all, original.IMG_9326

I believe Omega made less than a thousand of these!IMG_9327Another close look at the pushers.

  2. What rubbish
    The 145.037 was designed for NASA
    So the astronauts could use there Watches when in the space suits with latge gloves on

  3. Hello Christian

    ¡¡¡Excellent restoration!!!

    I have a Omega Telestop 145.037, please could you tell me why it is considered a rare watch?.
    Crystal 063TN5219TA, but Crystal gasket and Inner bezel ring I have no idea, please could you tell me the references and where to buy them?.

    Kind regards

  4. It’s a Telestop! Designed primarily for racing – I think for a specific racing team – the plunger / operator clipped to the steering wheel 😉

    I am very impressed by the transformation, and very jealous of the owner!
