Congrats with your find! A shame this movement is hidden.

What does that mean? Friction fit instead of riveted?

The detachable staff is a friction fit, and continues the principle of the earlier Chronometer Balance found on the V1, V2, and V3.

The earlier balance design integrates the roller jewel and double roller into the balance so that they cannot be removed, meaning that a restaffing will not disrupt their relationship. This design seems to take the idea even further. I would love to see a close-up of the balance removed to see how it works.

I think so too! I really enjoyed the pictures, but the balance was not closely pictured. And I want to see more anyway...

Seems Gilbert J. Easton was into mayonnaise.

What a beautiful watch; quite the nice purchase. I'm curious on your plans for servicing?

I'll work on getting some more pictures. As for servicing, I'm curious about my plans for that too. I feel like I should get it serviced and while I have a local guy who is fine, I'm just not sure if he is really the craftsman I need for this.

More pictures of the watch. I should have mentioned that this is a hinged case

Interesting. "MADE ESPECIALLY FOR" is also used on the 50th you linked to.
Wonder if Fred did this one too or perhaps by the purchaser.
Beauty.

Someone was keeping track of 50th Anniversary serial numbers.
Here is 024:

Hopefully I didn't get too much wrong in a reply.

Looks like you got it all right. That's an original late watch, and a beauty.

However, I never really looked at Art's SN 79 before. The more I see, the more I question it. It's obviously the wrong dial, and that makes me suspect the case too, since the dial has been redialed as a 50th anniversary (therefore someone had money).

Looking over my data (which is a bit thin for 50th, I'll admit), here is the distribution for Gruen gold cases with 7-digit SNs:
103xxxx -  1 (suspect; probably a marriage)
106 - 5
107 - 5
108 - 3
117 - 1 (SN 79)

Conclusion: I really need more data.

Case serial 1178002 would match up best with 1928-29. So I guess one question is when/whether Gruen had cased up these watches, or whether they reserved cases for them. We know there were several style lines of case as well, so it's not a simple question - plus these watches could be ordered to taste.

Looking into the other information I have for case serials 117, I think it could be original, but I'm inclined to be skeptical.

More data is always the correct answer. Yet, there is a trend that can be discerned and your info suggests that the #79 may not be a late sale but something else, and tbd. It is an outlier, to say the least.

Glad to know I didn't give bad information to the other thread.
