"RGM Pennsylvania Tourbillon .. Made in U.S.A."

by **R.Murphy** » Tue Apr 27, 2010 10:04 am

Our new "Pennsylvania Tourbillon" has been in the works for almost 2 years.

This is the first Tourbillon made in the USA in a series.

The case will be ready in the next 6 weeks.

Here are a few facts about the watch.

1. Bridges and mainplate are made of un-plated German Silver. Dial is made of Silver and jewel settings are solid gold.

2. The cage is very large for a wrist-watch, this makes it easy to see what the Tourbillon is doing. The case will have a side window.

3. The movement is hand finished and the Guilloche is of course made on one of our Rose Engines.

4. Do to the labor involved for us to make this movement we hope to make 3 or 4 in the next year.

5. This is a One Minute Tourbillon at 18,000 beats.

Thanks for looking.

Best Regards,
Roland Murphy

Hi Roland,

this is great to see, a USA made Tourbillion, I particularly like the dial side of the carriage and the Wolf winding work with the Wolf click.

Very cool, too bad it isn't going to be a higher volume production.

The overall layout looks very similar to what i had designed for my watch, is this watch using the train of the ETA 6497/8 movements? Or possibly the train from a Hamilton 10 size watch?

Also what are those 2 large brass pieces on the dial side?

I can't wait to see photos of the completed watch.

A beauty. I too like the wolf tooth wheels, gorgeous detailing
on this movement. The dial/front plate is very detailed and very interesting as well.

Hi Roland,

Congratulations on your tourbillon. I look forward to learning more about its construction and seeing it in its finished, cased up form.

Cheers,

Curtis

Very nice achievement I'm curious to see the final result.
Congratulations.

We are making the wheels, in fact we are working on new wheels with a different spoke design. the final watch will have these new wheels in gold, see below. Also below are pictures of the making of the stationary fourth wheel.

I wasn't suggesting that you didn't make your own wheels, i was just wondering if you based the train on an existing watch or if you calculated everything yourself from scratch.

Either way, it's looking great and i can't wait to see it's case and dial.

I concur with Paul- I'm curious as to what the brass pieces on the dial side are for. Did you place them there for aesthetic balance on the dial, or do they support something? Also, curiosity- what CAD program is that you're using?

As usual, your guilloche is wonderfully executed. I had the fortune to see some of your pieces at the caliber 801 showing at the watch museum, and I was really impressed by the quality of your guilloche.

I am a Pennsylvanian, and it's fantastic to see a USA made tourbillion from my state.
This looks quite impressive- I can't wait to see the finished cased piece.
