Hallmark seems to be an untapped mystery box of wonders, albeit most lower grade: I’ve seen A LeCoultre, Tissot and a host of others (General, Girod) there. Must’ve sold a bunch. But a black box to me. Has there been exploration on a past thread?
Going back to the transitions, I agree: Gruen seems to have a transition each time. The later United W Co ca1913 also have “Guar. Gruen”. Then transitions to “Gruen Guarantee” alone. Matts shown the 16-17 transition from that to WSC, and I’ve even noted a WSC 740 with the single word “Premo” still on the bridge. Fast forward to ca1921, and you’ve got the “Gruen Watch Specialties” movements—the last of the WSC.
My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more
