Automatic K-504 with an early Case Number

#1 Post by Mugea » Sun Jun 17, 2018 6:18 am

Just recently I bought another K-504. I had already one, but the other is more a parts watch. Anyway, when I compared the two I noticed something interesting:
K-504_08_1024x768.jpg

Both Case backs do have the very same number: 99644

Obviously, this is no serial number. But what is it?

Just to show the front of the new toy:
K-504_02_1024x767.jpg

OK, back to the backs. They seem to be more interesting.

Outer and inner flats don’t show any case maker’s mark or name. Unusual for a Hamilton of the 50s is the presence of “SWISS”. So I assume, the yet unknown case maker was located in Switzerland.

Now, what’s the significance of the number 99644 ? Let’s have a look in the 1955 catalog:
HamiltonCatalog1955_Detail_K-504.jpg

The catalog numbers of the variation with Numerals and dots are:

Bracelet: 996442
Strap: 996441

While the catalog numbers of the variation with Numerals, dots and markers are:

Bracelet: 996462
Strap: 996461

So, the numbers inside the back are the first five digits of the model number of the catalog!

Mark recently sold an awesome NOS K-504 with inner and out box:

I took the liberty to take one of his photos to show the sticker on the outer box:

@Mark: I hope, you don’t mind!

Interestingly, there’s mentioned a “CASE NO. HO 778” . What? On the watch(es) isn’t (aren’t) present any case numbers.

I don’t know, but it could very well be the variations ith Numerals, dots and markers are marked with the number 99646 inside. Maybe, also the models K-502, K-507, K-550 and K-575 do have such five digit numbers inside.

Is there anybody, who owns the other version of the K-504, or a K-502, K-507, K-550 and K-575, who’s willing to show a photo of the internal numbers (if any)?

Dan has presented on his blog a Franken a while back:

Interesting to note: the back is marked with a number 9958 (or 9956?) whatz also could be a part (first four digits) of the model number.

Any thoughts on this? I's appreciate any input!

Regards

Interesting topic!

I can confirm my 504's have the same 5 digits.

Additionally, my 502's have a similar pattern. Both cases say "0966" which matches the first four numbers in the catalog.

They also are lacking in a manufacturer mark or identity.

Hello GreenBayStamps,

thank you very much for showing your K-502 case backs! It’s a perfect match when you’ll turn them for 180°:

;)

Then, the number will change to

9960

What are, in fact, the first four digits of the catalog numbers for the K-502!

Regards

Martin

You're welcome! Something like this just happens. I guess, you'll know the "710 cap" joke?

:lol: :mrgreen:

Sorry! Seriously: does anybody has one of the other candidates (K-507, K-550 and K-575) and could have a look on the internal numbers (if any)?

Regards

Martin
