Cal 311 - Curvex Royal

with a black dial; Tue, 14 July 2026 03:42

There is another thread featuring the ID for the Curvex Royal. However, based on Kyle Roger's book, think that other watch is the Curvex Duke. This I believe is the better match to the Curvex Royal.

Model name: Gruen Curvex Royal
Type:
Period/date: 1936 or 1938
Gender: M

Case Maker: Wadsworth
Case Material: 14k Gold Fill
Case Serial: G 003773
Case Style no: 311 228

Caliber: 311
Movement Maker: Gruen
Movement Serial: 414564

Bracelet/Band: Recent replacement

This recent acquisition would be the Curvex Royal. Per discussion with Kyle it came with white and black dial. This is the black dial variant in a 14k gold fill case. While the ID on the black dial rests on Kyle's research in his book, the case style is still shown in print ads from the period.

Engraved Extra Precision Caliber 119

Sun, 28 June 2026 07:41

Hi everyone,
I wanted to share this Extra Precision caliber 119 movement with engravings and see what you guys think.
A few interesting points about this one:
1.It originally came in a solid gold case, but unfortunately, the seller melted the case down.
2.This is not a 50th-anniversary model. From what I’ve heard, the original factory description refers to this surface treatment as a "Guild style" finish.
3.There are visible milling marks on the edge of the bridge. It almost seems like it might have been modified from a caliber 117 to a 119.

Veri-Thin 'Master'

Wed, 25 March 2026 05:01

Model name: 'Master'
Type: Veri-Thin
Period/date: 1940s

Case Maker: Wadsworth
Case Material: 10K goldfill sterling silver back
Case Serial:G386170
Case Style no: 405-495

Caliber: 405
Movement Maker: Gruen
Movement Serial: 720275

Hello everyone,

I’ve been a long-time admirer of the craftsmanship and history behind Gruen timepieces, and I’m thrilled to finally join this community. As a newcomer to the world of vintage Gruen collecting, I’ve spent a lot of time reading through the wealth of knowledge here, and I’m eager to learn more from such an experienced group.

I recently acquired a Veri-Thin (likely a 405 495 case) on eBay, but I’ve run into a bit of a mystery. Upon inspection, I noticed the case back is marked as Sterling Silver. However, in the original sales posters and advertisements I’ve managed to find for this specific model, the descriptions usually list guildite back options.

Has anyone encountered a Sterling Silver variation for this model before? I’m curious if this was a specific regional release, a wartime material substitution, or perhaps something else entirely. I would love to hear any insights you might have on why this differs from the standard marketing materials of the era.

Additionally, the watch is currently missing its crystal. Does anyone happen to know the correct Watch-Craft brand number or a compatible G-S Flexo (or other brand) crystal model that would fit this specific case?

Thank you all in advance for your time and for welcoming me into the forum. I’m looking forward to being part of the conversation!

Best regards,

ytony2876

Pocket watch box

...for the person that doesn't really collect pocket watches; Tue, 16 December 2025 04:37

Description

Wooden box with sprung clasping closure for a pocket watch. Case is made of wood, with a single formed inlay of mother of pearl. Heavy lacquer applied to the top surface and sides of the case. The back is minimally finished. Inner case holder has a backing piece that allows for it to be propped-up as shown. Otherwise, lays flat. Has an inner pocket in the inside lid padding. No papers. No hidden compartment under the padding for the watch.

Precision marking to me suggests that this was for a high-end watch, with the matching diamond 'Precision' mark on the train plate. ca 1910 or so... based on this thread. However, we seem to have lost the image that Barney included. There is this ad too - https://vintagegruen.org/vgforum/index.php?t=msg&th=1568 &goto=11408&#msg_11408

Period:
Watch type: Pocket watch
Size: case diameter of 46.5 mm
Inventor: unknown
Patents: unknown

Box maker: unknown; made in Switzerland

The watch is there for size example of what fits. I do not have a pocket watch that I believe is appropriate for the case.
