The Veri-Thin 'Adams'

Tue, 31 May 2022 22:52

Model name: 'Adams' with expansion band -or- Nimrod with leather strap
Type: Wristwatch Veri-Thin
Period/date: 1940-1944; the movement serial number is date estimated to early 1944.
Gender: mens'

Case Maker: Star Watch Case Company
Case Material: goldfill on silver and rhodum plated sterling case back*
Case Serial: 090790
Case Style no: 406-459

Caliber: 406
Movement Maker: Gruen
Movement Serial: A328801

Bracelet: In both ads it is shown with an expansion type band for the VT Adams. The leather band on the watch as purchased, is 1940s era but is marked 'Waltham'. An obvious replacement. The ads for the VT Nimrod show a leather strap.

Other info: Identified in Shawkey's book as strap 418. page 131. Strap 418 is shown with a presumably an expansion band.

I found this in a pawn shop in Chicago this past weekend (May 29, 2022). Was an inexpensive buy. The tarnish to the case made me suspect that it was a war era watch with the silver alloy basemetal for the goldfill. Otherwise it is not the typical type or style that I collect.

Advertisment from December 1942 clipped from the Chicago Tribune

Although not named, it is the same model shown in this May 1944 advert from the LA Times.

Barnett's 1940s Decade book shows a very different 'Adams' in 1948. Could also be confused with the contemporaneous 'Stuart' but that has ridges that run onto the case sides.

*some debate below on my metal assessment of the back. There are certainly examples of this watch where the case back is marked as sterling. Other examples that are clearly stainless steel Guildite.

also... edits to reflect Barney's below addition of the VT Nimrod ID.

The Caliber UltraThin

Early variant, SN 41-42,5xx; Mon, 25 April 2022 23:46

Take two!

About 1,000 early UltraThins were made, between SN 41,000 and 42,500. They are impressively thin, and impeccably finished throughout. Some (perhaps half) are graded Extra Precision, like this one. It is unknown whether the later UltraThins in SN 148-150k and 185k are the same in all respects. There are also UltraThins at SN 13,7xx - another mystery how they compare.

Here's the dial. Showy, but understated.

The first issue makes its appearance - the movement runs +5 seconds a day across three positions in this regulator position. Bad restaffing, tsk, tsk. The "stud" by the balance cock is also too long, because it is actually just a screw that's been driven partway through the plate.

Ouch. Yes, that's epoxy, holding the balance jewel setting in place... who would do such a thing?! Both caps are messed up, and may not even be the right ones, or right screws... they sure don't seem to fit very well.

Of interest, the dial is marked with the movement serial number, and also has light cursive engraving that says "Gruen Su-" (cut off into the center hole) and then some stuff I can't make out (Gp 421???). You can kind of see it in the photo.

Don't get too carried away with this one - the delta across 5 positions is >250 seconds, and the beat error is so bad that it won't self-start, even at full wind. The dangers of shoddy watch repair... so much for Extra Precision!

The Caliber 250 Dietrich Gruen

Variant without wind indicator; Mon, 25 April 2022 01:18

About 1,000 early UltraThins were made, between SN 41,000 and 42,500. They are impressively thin, and impeccably finished throughout. Some (though not this one) are graded Extra Precision. It is unknown whether the later UltraThins in SN 148-150k and 185k are the same in all respects.

Of interest, the dial is marked with the movement serial number, and also has a manufacturer's mark. It is a sterile dial on the front.

EDIT -- this is not an UltraThin, it is a caliber 250 without wind indicator.
