I mentioned this a few weeks ago. I now finally have a set of pics. So let me share.
This is my first foray into the dark unknowns of early timepieces. The hallmarks date the case to 1900. It is English. It is a key wind and set brass movement and the seller describes it as an 1876 fusse from F. J. Spiller of Taunton.
None of my books acknowledge Spiller. I do not know how the seller's date came to be. But I do suspect this is a movement from a period where the manufacture of these pieces was not state of the art. It is vary solidly made and still works over a hundred years later. This may be a good example from the last days of English watches. Once Harrison got them started, they dominated the industry for around a hundred years.
One of the things that interested me a lot was the case. It is a solid piece of Sterling silver hand wrought.
But let's get into the pics...
It is a big piece that polishes well into a bright shiny fetish The dial is clear. The key wind hole is protected by a lid as is tradition.
(Aside: note the stamps.)
I confess to only a non-WIS level of knowledge of this movement. I got this because I wanted one before I retired.
If it really is a fusee, the chain is encased in a big barrel. The barrel is sandwiched between two thick brass plates held in position by brass pillars. The gear train is suspended between the plates.
And the balance wheel sits atop the plates, normally under a dust cover.
The dust cover is the first hint of the interesting case work. It has a steel arch screwed into it... evidently for reinforcing against some sort of distortion... or torsion for a snap back trick??
The case is Sterling and is well hallmarked with 3 sets of stamps by "JR" who also is not identified in an references I was able to check. But the 1900 date must make it one of their later cases.
This was case number 808. Since they are hand fitted it is important to keep the parts for the case together.
I had to refit the acrylic crystal back into the case and that caused me to marvel at the ability to make a very small but truly round and strong thin lip to a relatively thin bezel. It took a great deal of time under 5x magnification to do it. But better to be slow than sorry!
The case is, in fact, not manufactured from pure Sterling silver. I assume experience show such cases did not have sufficient strength at a critical part, where the case suffers a great deal of pulling during it's life...
So a steel insert was fashioned across the top third of the case and was screwed into edge.
It keeps good time most of the time. It does not appear to have a very long power reserve and does show an irritating tendency to stop. The seller said it was serviced but serviced and serviced for sale are often two different levels of 'serviced'. Anyway, my watchmaker won't touch it so this one is mine to baby. But I haven't finished my parenting classes yet so Spiller and JR's work won't be much more than a looker for a while.
