The caseback has 2 markings I've been unable to identify: a casemaker's mark "ML" and a dog/wolf’s head looking left with number 4 alongside. I assume the case was made by an external firm probably outside Switzerland. The case has fixed bars. If anyone is familiar with these markings, would appreciate any info you have.


lovely watch, the teardrop case is very appealing.

I believe the ML is a cameo type sponsor mark, to identify the case as it was present to some authority who assayed the case material as to its purity. My understanding is that the sponsor mark is applied first, then the assay mark is applied following gold content confirmation.

I was unable to find either the sponsor mark, or the wolfs head symbol with its number 4 following a quick search through a quick look of the online resources I have found. Perhaps others can help out. Consequently, I would agree with your belief that the watch was cased outside of Switzerland. The second link below shows marks cataloged from around the world, so with a fresh cup of coffee and some time, a deep dive into that link may provide the answer for you.

I believe you can get a COA from IWC for your watch. If you do, that may show you some clues as to the country the watch was delivered to, and may narrow your search.

some case mark links that I have found helpful are:

@Fallout Boy @Flatfoot Thank you both for your input. Further to my previous post, the only vague info from a few years ago I have about these marks was that someone who also has ML on their IWC caseback posted somewhere that it represents an unknown/unnamed Austrian casemaker. I've also read that the wolf/dog mark with 4 denotes a 14k gold case (and below graphic seems to confirm that). Hungary had marks with wolves but so do the Portuguese, as FalloutBoy mentions, so in all likelihood it comes from some place between the Atlantic and the Danube.

Nice! they are beautifully made, aren’t they.

The lack of any incabloc protection on mine, too, hasn’t changed my wearing habits at all. I’m careful in wearing any watch, and this one is no different. Do you wear yours frequently?
I'm probably a bit more cautious - like you, I take care with all of them, but while this is in my rotation, just, it only gets a few special outings a year. But that infrequency does actually make it feel all the more special!

Anyway, I've just sent it to IWC for an estimate for servicing, so maybe they can tell me something about it.
Hope you are sitting down when you get the quote. It will likely be double the value of the watch, if not more.

Damn... Really?

They've been very nice and polite so far, now perhaps I know why!

Well, if the worst comes to the worst they might be able to tell me something about the watch, and if the quote is ridiculous I can take the watch back and send it to watch guy instead..

2nd attempt

This is another watch that insisted I buy it
I think it was in the late 90s
it was sold to me as a 60s watch but looking at the serial no 1104191 it coud be 40s/50s any other info greatly received

Just wanted to share one of my IWC collection, a Portugieser reference 325
It carries the reminders of time and humidity, but the dial markings still shimmer at an angle.

This watch is almost identical to the original 1940 dial selected by Michael Friedberg in this article:
https://www.iwc.com/en/forum/five-great-portugiesers.html (one must configure/allow cookies&location for IWC site)

At wrist-to-eye distance the aging/flaws on the dial are much less obvious. 😀

This is an area where I'm almost completely ignorant, and I'd appreciate any advice, suggestions, or comments.

I've attached a few photos of a vintage IWC. The watch belonged to my wife's grandfather. Her grandmother passed away a few months ago at the age of 98, and my mother-in-law found this among her mother's possessions. My wife has fond memories from her childhood of her grandfather wearing this watch on Sundays and special occasions. As the engraving on the caseback signifies, the watch was a retirement gift to her grandfather, who spent four decades as a butcher in an A&P supermarket. My mother-in-law has gifted it to me, and to my knowledge it was never serviced.

From what I can see, the watch was appreciated and treated with care. The dial seems good, as well as the hands, and I'm guessing that the crown is original and something that should stay. My intention is to get the movement serviced, the case tidied up (but not polished), and the strap replaced with an OEM strap and buckle. Anything else? Other suggestions are very welcome.

I’m not sure on the model but congratulations and good plan of action. Enjoy

It’s good that you know the origin of the watch. Great heirloom. You have a sound plan but do make sure you take it to a competent watch maker.

I think this is IWC's model Ref. 810 A from the early 1970s. If you look at the third image/page in this scanned cataologue from 1970 you can see one that looks very like yours in gold, with a date feature (Ref. 810 AD). Without the date feature it is Ref. 810 A.
