Marked DG&S on the movement; Fri, 04 November 2022 17:17

Here is an interesting one currently on the swamp. We've always seen these Gubelin's and the relationship to the guilds but this one has the Gruen markings to go with it.

I guess, the „two diamonds” brand was used to mark the case material – in this case, 14K gold.
A good abstract of WBO’s history was published in the „Cincinnati Enquirer“ of June 28, 1951:

Gruen Superior Verithin (LV)

Tue, 19 July 2022 17:59

Model name: Gruen Superior Verithin

Case Serial: 308892
Case Style no: n/a

Caliber: LV2, 16j, with swan neck regulator

The bat box

Tue, 19 July 2022 11:57

Now this can be called an innovative and unique watch box. Wonder if they made just one...

A solid gold autowind presented to Cincinnati Redlegs slugger Ted Kluszewski in November 1955. This "box" should be worth some money...
