P1040555 This is a genuine triple crown chronograph! Someone decided that two crowns would make nicer pushers.. Watch is not running and needs some love.
P1040558

It’s also impressive how all 3 crowns are different.

P1040559

The dial is patinated and a little dirty, but overall good original condition.

P1040561

Well it made me laugh.

P1040562

With the dial removed you can see the setting/winding mechanism.

P1040563

I start taking the movement apart. It’s complete except the minute recorder spring.

P1040566

The movement reminds me of the 861 design, but uses more wire springs.

P1040570

Plenty of dirt lying around.

P1040576

Here you can see the gear train layout.

P1040577

The old mainspring.

P1090377

The movement has been cleaned and I’m seeing the balance moves freely after fitting the shock jewels.

P1090376

I fit a new mainspring in the barrel.

P1090378

The clean gear train goes back into the movement.

P1090379

Here you can see the setting/winding gears.

P1090380

Base movement almost back together.

P1090381

The movement starts ticking straight away after fitting the balance.

P1090382

When there is too much power in the gear-train the watch starts banking.

P1090383

The solution is a weaker mainspring.

P1090394

That’s perfect.

P1090386

The chronograph layers comes together.

P1090387

The minute recorder spring was missing so I made a new one.

P1090391

Movement back together.

P1090392

Base movement ready for dial and hands.

P1090393

Dial has cleaned up very well and looks very nice.

Movement back in the case looking great. The case has been restored at Replaiteit in Canada.

P1090398

Movement also has a dust cover. Entertaining as the three crowns were, a set of new pushers are much more practical;)

P1090400

Now that just looks fantastic!

I very much like the golden brown patina in the GP case!

Update: Just after finishing the watch I found a NOS jumper spring. I’m proud of my repair, but it’s not as good as the original part;)
P1090524

The new spring.

P1090527

Now the movement has the correct minute recorder jumper spring.

    BEAUTIFUL!
    What did you use to make the minute recorder spring?

      I used a steel centre seconds hand with a triangular point:P The triangular tip gives me material so I can slot it in place. I bent the shapes and then polished the finishes. It’s not that different from the original spring.
