Do I detect a stem-winder, a spring detent escapement, and at least one diamond end stone? Last quarter of the 19th century? @Bernhard J indeed has a flair for exotic timepieces! Perfect!

All correct. Hall marks for 1883. The watch has quite an unusual winding and setting mechanism for the fusee movement. The crown spins freely when the cover is closed; it only winds when the cover is open. The hands are set by pushing down the small gold button at 4:00. The button pops out again once the cover is closed via a tiny pin that is depressed by the closed cover.

Here is a photo of a duo in uno hairspring in another watch (signed Dent). It comprises a flat portion and a cylindical portion. It was thought to provide a better rate. A variant is the so-called triple overcoil hairspring, wherein not only one overcoil, like in the Breguet hairspring, is present, but a total of three overcoils (although not cylindrical!).



And here a triple overcoil (Penlington 1882) .

According to Marvin Whitney in his book on the marine chronometer, William James Frodsham and William Parkinson formed the Parkinson & Frodsham partnership in 1801. Parkinson passed away in 1842. William died in 1850, but the firm, being still in business in 1883, it was probably run by heirs. William James Frodsham (3rd generation, 1778-1850) was the eldest son of William and Alice Harrison Frodsham. She was a grand daughter of John Harrison, whose history in the development of the marine chronometer is well known. (Not an expert in genealogy, but does that sound like inter-marriage?)

The price on the 992B seems too good to be true. Especially considering that it is in the Hamilton (model 17 ?) case that our very own @DaveK is so enamoured with, and which he recently added to his collection.

The Howard # 11 at $400.00 seems high for that model, in spite of its apparent excellent condition. The # 11 is quite collectible (I have one), but many collectors look down their noses at it. Howard acquired the New York Standard watch company, makers of “popular priced” (reads as inexpensive) watches. One of the NYS models was developed into the 16-size Howard model # 11, railroad chronometer. The Howard version strongly resembles the NYS version. And thereby, collectors have a tendency to shy away from them. But I quite like mine. Like so many of my watches, it came to me with a history.

Get that Hamilton if you can. That's a good price and that is a clean looking watch.

The Hamilton description says the following. Note the last paragraph where it states the watch has high amplitude. This, apparently from what I can read, isn't good for a watch? Perhaps this is why no bids on it yet…

Perfect Christmas present This vintage Hamilton pocket watch, model 992B, is a true gem for collectors and enthusiasts alike. Made in the middle of the century in the United States, this railroad grade pocket watch boasts a mechanical (manual) movement with 21 jewels, a screwback caseback, and an analog display with an excellent double sunk Railway Special dial featuring Arabic numerals and a 12-hour dial.


The watch is in excellent condition and comes with a holder. With features such as a Reed Micrometer Regulator, Gold Center Wheel, Railroad Approved, and a gold-filled case, this timepiece is a must-have for anyone looking for a classic and reliable pocket watch. Add this stunning piece to your collection today! Comes gold plated fob


This pocket watch is running with high amplitude. like all pocket watches if this watch is dropped even once the balance staff can break . This fine timepiece will need a full service overhaul from a qualified watchmaker in the future. No guarantee on timekeeping. Thank you

Is there a bit of damage to the 24th minute of the Howard?
Yep. Great spotting. I checked all the pics. It doesn’t move with the angle of the watch. I’m going to hang in on the Hamilton and see if I can score it fairly low. It has some light scratches to the crystal that do change position as the watch is moved and photographed. I’m hoping a bit of light work with get those out.

I've spied a Howard and a South Bend at a little antique shop down on the courthouse square. I didn't have my reading glasses so didn't want to commit to one or both. Prices seem reasonable, way more reasonable than Ebay and I have no example of either brand in the pocket watch menagerie so I'm going back in there on Friday to see if I can sneak up on a "deal."

“High amplitude” doesn’t become serious until the roller jewel “banks” on the back sides of the pallet horns with the watch fully wound. The mainspring in a 992B is fitted with a “T” brace at the outer end. Substituting this mainspring for one that is too powerful, could be done, but unlikely, in my view. Whether high amplitude can be interpreted as “too high” could be determined at time of servicing it.

Appears to be a model 11 case

It is not a rare watch according to the pocketwatchdatabase site.

https://pocketwatchdatabase.com/search/result/e.-howard-watch-co.-keystone/1262929

But as dials go, I’ve seen worse. By the way, the Hamilton dial is single-sunk, not double-sunk! (But so is the Howard dial single sunk.) There is another series 11 being offered on the same site as the subject watch. It is listed at $425.00.
