The Model 22*

1913 to 1914

As late as 1910 there was no mention of a 12-size watch being made by Seth Thomas in any of the known catalogs, so it's interesting that the factory would design one so late in the game. The Model 22 debuted in 1913 with the Centennial Trade List, offered in just two jewel counts on nickel plates and available as a complete factory-cased watch only.

The Serial Number Blocks

40,000 Total

The Model 22 was produced in a single unbroken run of roughly 40,000 watches, the overwhelming majority of which were the 7-jewel Centennial grade. All of the reported examples are between SN 3,258,000 and 3,298,000, with one small block of the higher 15-jewel Grade 328.

The Production Dates

1913 to 1914

The first known record of the 12-size Model 22 was in the 1913 Trade List. It was advertised as part of the Centennial Line, one of three sizes, and continued in the 1914 catalog supplement, the only pocket watches still being offered by the company.

There were only two known grades; both nickel-plated and open-face but with different jewel counts.

The prices for the 12-size movements matched the 4 and 16-size movements in the 1913 catalog. The Centennial watches, which were sold cased, sold for $7.70 in plain 10-year gold-filled cases and $10.00 in a fancy engraved 20-year case. 

The Centennial Grade

The Centennial Series was a named grade produced in three models, including the 12-size Model 22 family. While the standard Seth Thomas movements have two different jewel counts of 7 and 15, the Centennial grade always carried 7 jewels.

The Model 23*

1913 Only

The Model 23 was the only known movement with a bridge design and was offered in four grades, including a 17-jewel Adjusted-3-Position with gold inlay on the plate engravings. It was apparently offered for the first time with the Model 22, and it's bizarre that the company would tool up to manufacture, not one, but two 12-size movements when their sales were slumping toward the discontinuation of pocket watches altogether.

Fewer than 5,000 of the Model 23 were made, making it the smallest production total of any of the known models. All of the reported examples fall into a block between SN 3,500,000 and 3,504,500.

The Production Dates

1913 Only

The Model 23 apparently debuted in the 1913 Trade Catalog alongside the Model 22. No prior publication has been found and it was not mentioned in the 1914 supplement, which listed only the three remaining Centennial grades.

Four grades were listed in the 1913 catalog and described in detail. The three higher grades came with ruby jewels in gold settings and a polished gilt gear train, and all four came with a micro-regulator.

In the 1913 Centennial catalog the 21-jewel Maiden Lane was selling for $50, so the $25 price tag on the 17-jewel Adjusted-3-Position Grade 28 as a men's dress watch was considerable. These watches were available in "very thin special" cases.
