    Help me understand Bremont's case hardening.

    I'm debating an MBII. Probably going to go used at this point if I do. Looking at a few that have been posted over the last year or so, many seem to have subtle marks in them, everything from bezel marks or small dings on the side, to strap changing marks on the lugs.

    Bremont makes a hard sell on it's hardening process, and many have commented that it's harder than Sinn or Damasko. I've owned 4 Damaskos, and while I'm not crazy about the color of their nickel free case, they NEVER scratched, dinged, or nicked. So what's the deal? Can anyone provide some clarity for me before I commit to buying a watch.

    Re: Help me understand Bremont's case hardening.

    Unlike Damasko, who harden their cases all the way through, both Bremont and Sinn harden only the surface layer of their cases. Sinn and Bremont each use their own proprietary case hardening process, Tegiment and B-EBE2000, respectively. Here's a little more on Bremont's B-EBE2000:

    All Bremont watches are treated for hardness with B-EBE2000 technology. During this special stage in the case production the metal is heat-treated and defused with carbon, then bombarded with electrons. The process dramatically increases the hardness and scratch resistance of the stainless steel. On the Vickers’ scale of hardness, for example, B-EBE2000 produces a watch case with a value of 2000Hv - approximately seven times that of the normal stainless steel used for watch cases.
    2000Hv is pretty hard, but again, keep in mind that this is only surface hardening, meaning that a nasty impact can conceivably penetrate the surface and scratch the unhardened steel underneath the hardened layer. Personally, I think that Damasko is the superior choice since they harden their steel through and through, a process known as ice hardening. Ice hardening achieves a Vickers rating of 800, which isn't as hard as Bremont or Sinn, but again, Damasko hardens their cases all the way through and not just the surface. That being said, I can attest that surface hardening is still pretty damn scratch resistant, having owned several Bremonts in the past. Nary a scratch on any of them. However, I personally think that ice hardening is a pretty impressive engineering feat, making it the method of choice in my book.

    I've managed to put a little ding on my MBII just at the lug corner. Maybe from changing the strap, not sure.

    I've read enough to know that Bremont's customer service and service dept. is pretty good to deal with. Many have said that they shipped their watch to Bremont only to have it come back with a new barrel and/ or case. If you still have the watch, you may be able to have the barrel swapped out. But your right in suggesting it's a weak link in the design. Have seen a few small nicks to those orange barrels.

    Re: Help me understand Bremont's case hardening.

    Also, realize that you cannot refinish a Bremont case due to the hardening process. That's not speculation, that's from the brothers themselves.

    That's unfortunate, but they can make it look like new at the next (or first) service!
