Developing the Tank / the Strap “Tank”
Sat, 18 September 2021 11:34
All of this Tank talk recently got me looking. Take a look at Strap 23. Sure looks like all the tank features: Bieser case, 997 caliber. Was there a Strap model made before rebranding to Tank, like Straps 37-40 before Quadron?
Brown leather Quadron service box

The hand of this box feels like real leather. Mine is missing the insert. I’ve seen another, with a late 20’s Quadron inside, and I’m thinking that’s what it’s for. Came with Wrist Watch guarantee paperwork inside.

Here’s a later caliber, found in style number 1046 cases (1960s?). The case & movement are made in France. Imagine my surprise to see it stamped for Alpina!

Here are the men’s and women’s boxes, I think early 1940s. Outer box style was used for several years with different interiors.

A new addition today. I'd like to give it a name, but I'm coming up with bupkes. I've checked the Master Book, 1927 Stock Record Book, and the 1920s advertisements thread to no avail.
Gruen Military Wrist Watch
Plate 23B Out o' Doors ; Wed, 18 August 2021 17:02
Here is Plate 23B Out o' Doors if you call it. I got this watch from Thomas (Timeticker) many years back, don't see him around today. The watch has a 870 15J Premo Rebberg movement. The watch just came back from a good COA, new mainspring and hands re-lumed. The hairspring was all "jacked up" and had to be reshaped. The upper cap jewel is cracked but keeps oil, was decided not to replace and risk getting it back to running OK level that it's in now.
1933 Gruen Advertisement Announcing Connection with Pan American Airways Clipper
I found this Saturday Evening Post ad. Is this the earliest Gruen/Pan-Am Airways connection? ; Wed, 28 July 2021 16:55
I have a large collection of Gruen magazine advertisements. In briefly reading recent postings of Gruen ads in the Forum, I read of the earliest evidence of a business connection with Pan American Airways and their flying boats was the 9 Nov 1942 ad in Time magazine (I have my own copy). However I found the attached 1933 Saturday Evening Post ad that Gruen was providing accurate wristwatches to pilots of the first Clipper airboat. A Captain Sullivan is shown at the controls of the American Clipper Sikorsky s-40 that connected the U.S. east coast with Latin America and the Caribbean. The Captain is shown wearing a rectangular Gruen wristwatch. I have an original page with this ad with publication date in my collection, so there is no question of its authenticity. There is more to the story about Captain Sullivan and Pan Am Clippers to be told if there is interest. SteveReference | 9 comments
