a pair of Walthams

#1 Post by JackW » Wed Aug 30, 2017 8:46 pm

Last month (July 2017) I had a good month with watches. A few eBay purchases, estate/yard sale finds and even scored something good that the Colorado NAWCC regional.

In these were two Waltham products: A vintage car clock and a Depollier Khaki wrist watch.

I'm not interested in collecting clocks. Nor am I overly interested in pocket watches. The car clock was in expensive and seemed interesting. It is basically an over sized (37 size) pocket watch movement. My initial inspection revealed that the balance while in good shape was missing the roller jewel. Takes a #50 long roller jewel. An easy fix, but wasn't easy to track down.... finally got one in a lot of vintage roller jewels I acquired from a fellow member of the local NAWCC chapter.

The balance with a missing roller jewel...

well, not all of it was missing. It was broken off and looking closely you can see the nubbin' of what is left.

Here is what it looks like in the front:

Here is the back side of the movement; 7 jewel model 1910. Seems nearly three-quarters of a million of this model was made.

In disassembly of the movement, I got stuck with the main springs:

They're huge and I do not have a winder large enough to have replaced them... I cleaned the arbors and placed them back without further cleaning.

The train in these is pretty neat. Its in-line:

Anyway, it now sits on my bench. Was thinking I might mount it in my Jeep. That however is a likely recipe for a broken staff with the way I drive...

So, that brings us the the Depollier Khaki I happily snapped up at the Regional...

This is, it as I found it at the regional. Heck, I took this picture a few minutes are buying it.

Inside is a 7-jewel Waltham model 1907, grade 361. Serial indicates production about 1917.
Here is is with the balance being checked for shake after I had the jewels out for cleaning

Cleaned up the metal dial. Also took the hands, sanded them to remove the rust , polished them and re-blued...

I used luminova to re-do the dial and hands, but I add a material for an 'aged' look...
it glows:

Lovely work Jack!

I can't imagine you'd break the staff in your jeep though.

The Depoiler looks brilliant, its nice to see a metal dial in great condition.
