Guys this will not be as durable as SS or Ti but the point of the Bronze watch is more of a statement piece. It will hold up rather well and the price point here is awesome. If at the time I am done with my home improvement stuff and updating my home computer network I'll likely jump on this. Have a few more things to do. That is why you all have not seen me buying watches. But may get back at it soon just allot slower for awhile.
Like that bronze Anomino one of my doctors last year had one. Very sweet watches.
Since looking at the numbers it seems the alloy to be used, UNI 5275, aka C95520, is very strong and hard, perhaps stronger and harder than the typical stainless steel used for watch cases.
One source list the properties of C95520 as (from nbmmetals.com):
Tensile Strength: 125 KSI min.
Yield Strength: 95 KSI min.
Elongation: 2% min.
Brinell Hardness: 262 (max?)
The more commonly available C95500, suitable for gears and bearings, has these properties:
Tensile Strength: 95 KSI min.
Yield Strength: 42 KSI min.
Elongation: 10% min.
Brinell Hardness: 190 (max?)
And although there are variations depending on the source, here are properties for a typical 316L stainless steel (from AZOM.com):
Tensile Strength: 70 KSI min.
Yield Strength: 25 KSI min.
Elongation: 40% min.
Brinell Hardness: 217 max.
This statement is also interesting:
Heat Treatment of 316L
Solution Treatment (Annealing) - Heat to 1010-1120°C and cool rapidly [water quench]. These grades cannot be hardened by thermal treatment.
I'd like to see actual numbers for the materials Benarus use (both the bronze and stainless steel), but at least you can see it is promising for the bronze cases to meet and perhaps exceed the scratch and ding resistance of stainless steel cases.
