I've been keenly following developments in case/bracelet technologies, especially wrt scratch and ding resistance. I think I'm willing to spend a bit more if it means the watch will look new for a long time.

Having said that, I would like to set up this thread to keep up to date with:

1. Current technologies utilized for such purposes on watches.
2. Current models with said technologies.

First, the methods:

1. Hardening the surface - Perhaps the most famous is Sinn's much vaunted Tegiment process on steel. Other similar treatments include Citizen's Duratect and Seiko's Brightz on Ti.
2. Hardening the metal - Damasko's Famed Ice Hardened Steel Process.
3. Coating with ceramic - Made famous by Rado.
4. Coating with DLC - Diamond Like Carbon. Citizen and Casio apply DLC to many of their top end models. Seiko calls their version Diashield. Recently, Ball introduced some models with DLC treatment.

Next, the watches:

Ball:
Engineer Master II Diver TMT: DLC Ti (limited edition of 2006 pieces)
Fireman Night Train: DLC stainless steel

Damasko:
DA36/37
(Ice Hardened SS)
DC56/57/66 (Ice Hardened SS)

Sinn:
756/757/856/857 (Tegiment SS)
U1 (Tempus LE)

Bremont:
???

Rado:
??? (Ceramics)
??? (Tungsten)

UTS:
??? (DLC, Kolsterizing)

Seiko:
Spirit: SBQJ015/17/19 (Diashield Ti)
Brightz: (Brightz Ti)

Citizen:
Attesa (Mostly Duratect Ti)
Attesa ATD53-2834 (DLC Duratect Ti)
Attesa ATP53-2704 (DLC Duratect Ti?)
Attesa ATD53-2832/33 (partial DLC/Full Duratect Ti)
Chronomaster (Duratect Ti)
Exceed (Mostly Duratect Ti)
Exceed EBJ74-1724 (DLC Ti)
Promaster (Mostly Duratect Ti, some have partial DLC)

Casio:
MRG series (DLC Ti)
Oceanus (Casio's version of Duratect, with additional sapphire/DLC bezels on some models)

Care to add to the list anyone?

Additionally, under Damasko, are there actually DA 56 and 57? I can only find evidence of DC 56 and 57, both of which claim to be "ice hardended.."

I had seen a very lengthy discussion of this back in the german watches forum. A search might point you in the right direction.

One guy even went to far as to scratch us a Sinn I think, with a nail. Crazy.

Me again :) Sorry, but these are the watches that interest me most [ the scratch "proof" ones ] .. Check out this Damasko DC66.. also purports to be "ice hardened"...

http://www.gnomonwatches.com/images/DamaskoDC664L.jpg

anyone own one of these or any of the Damaskos/Sinns? I need attestation as to their manufacturing processes efficacy as it relates to scratch resistance..

Adam
Thanks. It was my mistake. Didn't notice the change from A to C. Noted and corrected.

Titanium is harder but - there was a reason why 316L steel was developed.

We must remember that the steel used in a watch goes under many different environments and not necessarily one "hard" aspect of the steel is good for every condition.

There are many actually. Some include the new GMT:

Current models:

Perhaps a Google search or on Watch-Tanaka will help you track down older models.

Ti is stronger, per unit weight than steel. Its surface hardness is actually lower than SS.

316L wasn't developed as an alternative to Ti. It wasn't developed for use in watches too.

I don't understand the point you're trying to make regarding the 'hard' aspect.
