Any History on This One

Looks like a Baylor Hebdomas pocket watch. From looking, Baylor appears to be the brand name for watches of the Zales jewelry group based in Dallas Texas. Linked with heuer they produce some nice watches.

There are various types of the Hebdomas in different styles built possibly in the early 20th cen

Baylor was one of about 150 brand names used by Benrus Watch Co of Chaux de Fonds.

Most of the engraved words are in French. 8 JOURS is 8 Days

If you are thinking of taking it apart. First let the power down. After removing the hands. You unscrew by means of turning the centre part with the two big holes.

Thanks OH. I actually have another old Hebdomas and had to make a special tool to unscrew the center part. I made a complete video on cleaning one of these. With the other Hebdomas, I tried to replace the hairspring and I was way too powerful. Still need to try again with a lighter hairspring...perhaps do the 1/2 inch drop test for strength.

The brand is not as rare as you may be prepaired to pay for. Should you come to need parts you don,t want to make, good chance I can find inexpensive parts.
Best wishes
 
 
 

These watches are usually going for +500USD on eBay.

    • You often see the term used on old watch part boxes.  Staffs for bracelet watches, timing washers for bracelet wstches etc.
    • The Boro has changed quite a lot over the last 20 years, and not for the better. I actually moved out of the town 15 years ago to a small village not far away. Thanks for the pdf! Looks a great read. I'll get it printed today and put it on my work bench!
    • Not having all the fancy equipment, this is a way I came up with. I never said it was the best, the most ideal or the safest way. Working on balances is always a delicate task whereby full concentration & common sense should prevail. I was well aware of the "dangers" / short comings involved, hence my "warnings", as quoted above. The balance wheel of the Omega was nice true, flat and one could clearly see how much gap there was left before the grinding wheel would touch the balance wheel. I stopped when the generously applied diamond paste started to touch the rim of the balance wheel, which turned out to be with a seat thickness left of 0.1mm. Tapping the remainder of the staff out went easy and flawless. My idea of penning this article was to show/share a way which, in my case, perfectly succeeded. If deemed to risky, or if the balance wheel is not true or has a wobble, other methods have to be followed.
    • I loved his explanation of a teardown 😅 Ex military Richard Perrett, pretty knowledgeable guy.
    • I also see a bit of danger for the wheel, at least you have to keep away from it and may get a too thick rest ring. My rest rings are about 0.05 mm. Better way would be a grinding wheel touching the staff with its circumference. Frank
