I recently acquired this 16 size Waltham 1908 Model Riverside Grade, serial number 27634141 which dates the watch to circa 1932. It has 21 jewels mounted in gold settings, adjusted to temperature and 5 positions, with an Ohlson 1908 patent regulator. According to the Grey Book there was only one run of 200 hunter 21J Riverside movements made in the 1908 Model,(27634001 to 27634200) making this quite a rare watch? In fact this is from the ONLY run, as no open faced Riverside 1908 Model movements were produced(not to be confused with the later 1621 Riversides).
The watch was shipped to England where it was fitted with a typical English dial and is housed in a gold filled Dennison hunter case.

Movement.

Hunter cased.

I'm a huge fan of this style as well as a fan of the Dennison case. Your watch appears to be in fantastic condition.

Yes it is in very nice condition Paul, and I also like the rather plain English style single sunk dial.

Peter, that's a nice and really rare Riverside! I personally have never seen a 5 position 21J Riverside, let alone a hunter.There are a lot of open face 21J Non-railroad grade Riversides, made around the same time, but those are only temp. adjusted, and are marked "jeweled main wheel" on the ratchet wheel, and only have a simple regulator.They are always mis-represented as a RR watch on auctions.Yours, if it was lever set would be RR grade, but being a hunter it may not have been approved.Were those Dennison cases still being made at that time? Thanks for showing it...Ted.

Ted, Dennison's started producing their gold filled cases in 1892 in three grades Sun, Moon and Star. Sun being the highest grade and Star the lowest. They Sun grade was discontinued in 1928, but the Moon ans Star grades continued until the outbreak of the 2ns World War in 1939. This is a photo of a page from a brochure produced in 1935 advertising Waltham watches in Dennison cases of various metals.

This Riverside movement is housed in a Dennison 'Moon' case and just below the serial number you can see the double digits 35 which is possibly for the year of manufacture.

Thank you Peter for the case info.I had no idea that Dennison was still around at that time.I meant to say in the other post,most of those Riversides like yours are 19 jewels,so yours is pretty unusual.Take care, Ted.

Ted, Dennison's went on producing cases for a good bit longer, making mostly gold cases. They finally went into liquidation in February 1967 after 93 years in business.
