I've done some research on this and the bronze alloy (nickel aluminium bronze) has very similar properties to stainless steel and even machines the same.

I visited Jura last week while on holiday in London and have decided that I really like the bronze cased Anonimos. The orange D-Date ticks all the boxes for me (I need a watch that tells me what day it is as I keep forgetting). My one concern is the toughness of this case material, is it easier to scratch/dent than regular stainless steel?

Cheers for that, I have machined regular bronze before - it was nothing like stainless steel. I guess that clinches it for me, I'd better start saving....
There is at least one member on here with one, hopefully he'll be along soon.
I recently was lucky enough to see it and really liked the way it had tarnished to give it a really interesting finish.
Unfortunately I didn't really inspect it for every little ding so you'll have to wait for Jon.
Get some of this and then apply some lacquer 8) :P

Don't you need to use a negative rake angle when drilling Brass and Bronze so different to SS? :shock:
EddieThe handling of aluminium bronze need present no difficulty to the average machine shop, and
can readily be machined using modern tools, steels and the correct workshop technique.
Definite values for maximum feeds, speeds and depth of cut cannot be stated since these are
influenced by several factors; the equipment being used, the operator, and his experience in
handling the material. The various recommendations may be taken as representing a reliable
average, offering maximum production with reasonable tool life and efficiency. Whilst,
therefore, some machine shops may fail to achieve the recommended values, others will exceed
standard practice.
Aluminium bronze must not be confused with free machining brass; rather should it be
considered as a bronze with mechanical properties similar to those of a high grade steel.

I've had mine for about 2 years now and no dings. OK, so I'm careful with my watches, but I'm sure if it were much softer than steel I'd have marked it by now
Mine still looks good as new at 13 months.
In fact, as it weathers it looks better than new.
BTW Rich, you should have gone with Black :lol:
You know, I was about to tell you that you should have gone for orange 8)Originally Posted by b11ocx

Thanks Eddie.
It appears the watch should be slightly lighter than stainless 316L as the bronze has an S.G. of around 7.58. 8) compared to 316L at 7.83 S.G.
I never saw it - the design on the first page and the bronze design are magnificent creations.Originally Posted by swanbourne
Please tell me that at least one of these designs is still in the works somewhere?
Have we given up on the idea of a bronze Dreadnought?
It very much depends on the mixture of the alloy. Aluminium Bronze is often used in Marine applications; ships propellers, and propeller shafts, Aircraft landing gear. Its not about hardness alone, more important is its tensile strength which is higher than most stainless steels for that reason alone Aluminium Bronze is used in high load bearings. Don't know if it would work for watch cases but bearing sleeves and other bronze products are usually cast and then machined rather than stamped out.

Though Rich would say go for the orange, as it opens up waaaay more options when it comes to his lovely straps :lol:....plus it is a cool colour on this watch 8)
Maybe bronze can be metal injection moulded (MIM? 8)
Plus, the black dial variant is just soooooooo common :mrgreen:Originally Posted by GingerMagician
Not all the black dial variants are that common :wink:Originally Posted by Toshi
(sorry Jay for continuing to use your old picture - I keep forgetting to do my own )
That's my favorite dial.Originally Posted by Stanford
I do like that a lot......Originally Posted by Stanford
Stop it Bob, I miss the damn thing and that doesn't help :twisted: :lol:Originally Posted by Stanford
Don't you still have the rare Gold/Drass-cased version to console yourself with? :DOriginally Posted by Jay
No, that one has departed too. I must be crazy :lol:Originally Posted by GingerMagician
Does anybody with one of these pieces suffer any green skin reaction, or would the particular alloy used prevent this?
Cheers.

Case back is stainless steel and raises the watch slightly from the wrist, so no bronze comes into contact with your skin.Originally Posted by DMR

It's gold & steel, not gold & Drass.Originally Posted by GingerMagician
Hmmmmm, I wonder who has that one now?
:D
Rich, there cant be many watches you DONT own by now :lol:
You wouldn't say that if you could see my "to do" list :lol:Originally Posted by b11ocx
What a beauty!Originally Posted by Toshi
Of course I did! I just forgot having read it. Happy that it is still in the backburner....Originally Posted by swanbourne
I hope you are referring to the incredibly nice watch and not Rich's wrist. :lol:Originally Posted by JHM
Jon, so you don't like his wrist :lol: ?
Hi Wild Rumpus
I have in my hands right now one of the original Limited Edition Anonimo Polluce bronze, orange dial watches.... it's #0x/50.
I bought this watch new, before Anonimo even came up on most peoples radar... and I can tell you that it has been a joy to own, is stunning and has had many admiring comments.
To answer your queston... I have found the bronze case to be superior to steel in resisting surface marks or scratching... mine looks exceptional.
When first had the watch I kept it polished, but now I have left it to oxidise and I much prefer it in the deep, matt brown colour it has slowly turned. Of course, it could be polished back to gleaming bronze easily (in fact you can paint it with a cleaning paste that will do the job and then wash off).
Another little thing which gets overlooked in this day of Divers watches... it's waterproof to 100ATM - YES... 1000m!!! It is a very elegant watch to achieve that kind of pressure resistance when compared to some of the chunks out there.
I was actually considering selling mine as I haven't worn it for a long time, but all your posts have made me think again!
Mark
Cheers Mark, it all sounds good, nobody who has owned one seems to have a bad word to say about the case material (or indeed the watches themselves). The D-Date is only 500m water resitance, but I guess I can live with that :D

If you ever decide to flip it, etc etc...
I've my eye on a bronze watch too, a Gerald Genta Gefica
One day it will be mine...!
Arr but is that solid Bronze or PVD?
