What does this one tell us?

[Greg Frauenhoff]

A rather ordinary looking low grade movement, but does it have any unusual features? Do they tell us anything interesting?

cool hairspring holder :thumb: goldscrews i think, nice balance cock..... but one repaired jewel... good work

[RON in PA]

Early stem winder? Who was mister Studley? Where are the mean time screws?

[watchfriends]

Where are the mean time screw?

good but i think thats the watchmaker regulation? Ancre escapment?

[Luca]

Looks sort of transitional as you often see that type of balance cock (w/ flat hairspring) on series I (keywinds) but this has elements of series II with the stem winding. Is the balance cock original?

[Fred Hansen]

Isn't the name in the Hampden serial number range more typically just "Studley" with the full "Theo E. Studley" name seen more often in the New York Watch Co. serial number range?

I think the male stem, early lever-set mechanism, and thick center wheel pinion are interesting features.

Balance screws look gold to me as well, but it wouldn't want to swear that they are without testing somehow.

None of the jewels look to have been repaired. Which one are you refering to?

Yes, any early stemwinder.

Theo. L. Studley was an officer (and presumably a stockholder) for the New York Watch Co. at one time and had a NY grade name after him. Hampden carried on with some of the NY grade names.

No mean time screws, but it may have never had them. A mvt close to this one in s/n and probably of the same grade also does not have mean time screws.

Yes, lever set, but anything uncommon about the lever?

Balance bridge and balance wheel are original to the mvt.

The Hernick and Arnold Hampden book has a little info on this type of mvt, but they don't discuss it much.

Anything odd at the center?

Any guesses about jeweling? (I haven't had the dial off on this one yet, but I did check the similar one close in s/n and I would guess that this Studley is jeweled the same.)

[Greg Frauenhoff]

Fred, you posted as I was preparing my reply.

Yes, the full signature "Theo. E. Studley" is uncommon for Hampden period watches.

Yes, the center pinion is thick, whcih means?

in german the watchmakers sometimes used this "new" jewels but that is a american watch so "i don't know". Ordinarily that must be a natural stone

[Greg Frauenhoff]

Hello,

The circle is a decorative engraving on the plate around the small hole for the 3rd wheel pinion. It may have served the function of an "oil-guard" as well (prevent oil from running onto the train plate). There is no missing or replaced jewel.

[watchfriends]

okay :) If i see an other movement like this i will believe :cool:

[HenryB]

Greg:

I have it identified in my database as a Studley 9 Jewel.
Be very interested in your jewel count, as the Hampden Watch Book by Arnold/Herrick only identify 9 and 11 Jeweled Studleys.

Although the Hampden Watch book identify the grade as "Studley and Theo E. Studley", the Theo E. Studley could have well been a PL.

Or for that matter, both the Studley and Theo E. Studley could have been PL's, just do not know.:?|

Incidently, I have looked at over 5,000 Hampdens on ebay over the last year. First time I have seen a Studley of any sort or marking.

Thanks for showing it. :clap:

[Greg Frauenhoff]

Henry,

The grade "Theo. E. Studley" is among those shown in an 1878 Hampden ad. It was also used as a grade name by the NY Watch Co., Hampden's immediate predecessor. So it's not a private label.

The other mvt that I have near to this one (#100812 or so) is a private label and has 11 jewels. I will check out this Studley later tonight and report on the jewel count.

[terry hall]

watchfriends,

if this was a 7 jewel movement, all of the 'settings' would look like the one with the arrow...

they would be unjeweled pivots...

you asked about the lever...this is not a conversion to stem wind and lever is it?? :?|

thick center pinion = sweep second???? (just a guess ... ) edjamakateme

[Luca]

It doesn't have an Abbott's does it?

And thanks for posting - interesting stuff.

[4thdimension]

Fat center pinion = Bank vault watch?????
-Cort

[Greg Frauenhoff]

I wouldn't consider it a conversion from key wind to stem wind, but simply an early (the first?) version of a Hampden stem winder. The design may have started at NY, but I haven't seen it used on any New York 18s full plate mvts (all such that I've seen are Key Winders (this doesn't include the 3/4 plate mvts of course)), but one never knows what is lurking out there in watch land.

The large end of the "center pinion" is actually the end of the arbor for the minute hand which runs through a hollow center wheel staff. A similar design was used by E. Howard and Lancaster and maybe other makers.

Hernick and Arnorld show a good close-up of the center wheel assembly in their excellent book, but they have no other discussion about it that I came across.

I removed the dial and the watch has 11 jewels (2 pairs for the 4th and escape pinions).

Some old watches (even just movements) never cease to amaze me.

[Tom Huber]

Greg, I have a movement like this that I just bought from Fred Hanson. The info on this type of early movement is on page 17 of Hernick and Arnold's book. The center wheel is known as a "hollow center wheel. It has the extra large arbor. The cannon pinion is also quite different. The setting lever is the swing type of lever. These must have been an early proto type for stemwind movements.

Tom

[Greg Frauenhoff]

Tom,

I would call these "early stemwind model" (perhaps even Hampden's first production stem wind model), but not a prototype since there are a number of them known. From H & A are #s 75344 and 100609. I have #s 100695 and 100812.

What # is yours?

Greg
The only advertisement for Hampden I have access to is the Hampden 1878 advertisement, shown on page 32 of the Hampden Watch Book.

The Theo E. Studley shown is this advertisement is No. No. 43466, and it is under the Caption of a New York Watch Co. Product, prior to them changing the name to Hampden.

Is the advertisement you are referencing ?

[Greg Frauenhoff]

Henry,

Yes, that is the Hampden ad I refered to.

[Tom Huber]

Hi Greg, The SN is 75,138. I've posted a pic. When one looks at the watch, the balance cock does not appear to match, but have checked it and the SN matches.

Tom

[Greg Frauenhoff]

Tom,

Neat watch.

I can't quite make out the name on the train plate. Can you let me know what it is?

[Tom Huber]

Hi Greg, The name is "Standard".

Tom

[Greg Frauenhoff]

Thanks Tom
