I've seen "alumigold" and "aluminum gold" but goldinum sounds like it would be the same thing. No gold, but an alloy of aluminum to look like gold. Is the case very lightweight?

I would think its along the lines of silverode, Silveride, silverore, Silverine... None of them contain any silver, just nickel alloy intended to look like silver.

Also, it would help to see pictures.

It actually test as gold 14k and its soft like solid gold cases,I'm sure it's filled but I've never ever seen a marking such as this 1,ive seen guaranteed permanently,one quarter gold pride of elgin and even g.w. ladd cases with 1/2 gold content but never 1 that says wears like solid gold,it has the initials M.S under it for Meyer & Studeli

I've seen goldinum described as a cross between gold and platinum. Don't know whether to believe it or not.

Just a surmise ,but it may be gold alloyed with aluminum. In the late 19th century aluminum was as valuable a gold.

Oh wow so now I understand why some cases was made out of aluminum from that time

After doing a lil research I would agree that its either gold and platinum or gold and aluminum,but i would lean more to gold and aluminum alloy mixed but a solid gold case

Oh wow I never expected a mix of platinum,it definetly contains at least 14k was tested with kee gold tester
Kee testers are great for quick sorting. We have several. But 120% they cannot be trusted for gold filled or heavy PLAQUE. Just DON'T!

Ran down the rabbit hole looking up Goldinum

If you can locate a copy of Iron & Coal Trades Review - Volume 105 - and look at Page 34 , the watch maker, Meyer & Studeli, is referenced

Book reference that has the registered name of Goldinum
Iron & Coal Trades Review - Volume 105 - Page 34
books.google.com › books
1922 - ‎Snippet view
Web link
Goldinum Brand - Metals - Google Search

Snippet from Google
Found inside – Page 34
The month of May gives the best results since Metals , Limited , Brentford Foundry , 2 , Glenhurst “ GOLDINUM BRAND . ” — Metals . Meyer & Studeli November last , but even with the slight improvement Road , Brentford , Middlesex . Société ...

I have not found any reference to alloys of gold and aluminum but I did find reference to a gold aluminum inter-metallic compound. I have some limited background in this. Usually, inter-metallic means nasty physical properties and the gold aluminum inter metallic is also called white plague when it forms in making semiconductor devices. It is formed when aluminum or gold wires wires get bonded to a surface that has gold or aluminum in it (whether it is gold on aluminum or aluminum on gold, it is bad.) A while brittle material forms and destroys electrical contact.

Oh wow,I don't think it's any aluminum in it,I'm pretty sure it's made of gold and platinum mixed,the watch is from the 1920's which is the time platinum exploded on the market
