·I got to conferring with a Patek NY employee the other day, and the subject of spring bars came up. He said they endeavor to fit solid gold bars to all of their watches, because stainless bars eventually deform (ovalize) the lug holes on 18K cases. Whether this is due to traction stress from the bands, or rotary abrasion, he could not say.
Anyway, I checked one of my unmolested bumpers, and the original spring bars appear to be brass. On a similar condition Centenary, they are solid gold (had them tested).
Brass I believe is softer than stainless, so this I assume would be comparable to the solid gold. But have any of you seen this lug hole deformation alleged to occur with stainless bars on solid gold cases?
Thanks,
