Thank you for sending the picture. I think this is a caliber V3, definitely not caliber 50. But other than I assumed the catalog should have answered the initial question. I am 90% convinvced that it is the gold weight of the case.

How about a dial pic and we can attempt an ID?

Hi Mike,

it is all here:

Found it out too late, otherwise I would not have asked for the movement pic.

We need more information to tell you more.

The main picture is missing... that of the dial and the watch as a whole. Dunno how to ID an invisible watch. :?

Well then, by all means traipse on over to some place where the answer is willing to be posted. :|
That sounds derogatory, Mike.

More to the point of the OPs questions:

I just received my copy of the same catalog that Barney posted pages from at the VGF. Reading the German for me is like trying to eat steak with no teeth. It can be done (I've seen it actually) but it takes time to ingest it. I could cheat I guess and have my wife read to me. Need to find the section that Barney is referring to.

Anywho....

I like the idea, Barney that the 50 is the case weight. It is a good guess... As a side note, it made me wonder if the number 42 inside of my sterling Gruen marked pocketwatch was the answer to everything... including the case weight rather than being a serial number.

Alas, the weight of my case is 23g of silver. 42 in my case, may actually be the serial number.

But....
this one: 232638355573 is 14K and has 70 stamped into it.
this one: 272511692364 has 48 stamped into it.
this one: 382307181150 is 14K and has 110 stamped into it.
and lastly...
this one: 122839035604 is 14K and has 50 stamped into it.

So, I think I agree with Mike B on this one, that it is part of the serial number. HOWEVER.... after looking at most of the Alpina pocket watches via eBay's finished auctions, there is one thing that sticks out to me...

The goldfilled and sterling examples I looked at, none were marked with this secondary number, so it might actually be something specific to solid gold cases.

HPS, if you put your watch on a scale, the weight of the movement and crystal should be 38g. Based off of mine which should be identical to yours. Is it a V3 or V4? I've been under the impression mine is a V4.

Hi Jack. Barney sugested it might be a caliber V3. The total weight of the watch is 61 grams.

I would not argue about the movement being caliber V4, I am not just 100% sure about the differences between V3 and V4. Just followed the description of the gruen.watch website. The V3 is said to be "PRECISION" marked whereas the V4 is not (reference 1918 catalog).
Jack, the weight of the cases is mentioned on page 63 of that catalog. Glad to hear that you received it! I am convinced that the gold weight is marked there. And that it was only done on the solid gold Alpina cases in conjunction with the serial number. In cases where the short number is a stand alone number it more likely is a serial number. And as said, only valid for solid gold, because the customer was offered these case classes. I have also seen 80 90 110 stamped in there as well as 24 in a ladies pocket watch. Unfortunately I do no own a solid gold Alpina for cross checking the theory.
