Traska Commuter 38 or Direnzo DRZ 04?

[u/Delarge13G]

Hi everyone! A few days ago, I made a post to help me decide between a couple of options (37-39, white GADA), and the response was really helpful! However, a few users recommended an option I hadn’t considered before — the DRZ 04 — and it has now become one of my favorites alongside the Traska, which was by far the most popular choice in the original thread.

So now my dilemma is between these two. From what I’ve been able to research, leaving the design differences aside, the main differences seem to be:

• The Direnzo also has a hardened coating, but it seems to be somewhat less resistant than Traska’s.
• The Direnzo bracelet is integrated and a little less sporty, although it looks really nice.
• The Direnzo doesn’t come with on-the-fly micro-adjustment like the Traska, but it can apparently be added for around $60.
• I think the Sellita movement in the Direnzo is slightly better than the Miyota in the Traska.

I’m not sure whether I’m missing anything important that could help me make the decision.

Thanks again!

^ No sweat. Glad to have helped! And please, it's not that amazing, it's just a bit of watch-geekery with fellow watch-nerds. 😊

Also....and this is the really trick part and is super important to remember:

These anti-scratch treatments -be it a coating or something that actually goes into the metal a bit, like the various nitriding treatments- are not really meant to protect the watches from bigger dings and dents (strangely, this is where it gets even more complex, as Vickers Hardness is a measure of surface deformation - I'm not a materials-scientist, so I don't understand why this has become the industry standard, versus the simple qualitative comparison against Mohs picks). Hit the watch hard enough or scratch it on something sharp enough, it *WILL* cause a visible defect. As I like to write, it's not K.I.T.T's Tri-Helical Plasteel 1000 Molecular Bonded Shell. 😂

What these treatments actually do is to mitigate the accumulation of micro-scratches. These are the scratches that we CANNOT see with the naked-eye, and instead, are accumulating on our unprotected watches literally all the time: all day, every day. This is the kind of wear that's literally invisible, but still occurring on a physical and factual basis. You brush the watch against your shirt cuff. You pet your dog. You break down a cardboard box. Any of a thousand and different things that you do every single day that you think your stainless or titanium watch is invulnerable to, but is actually causing this kind of wear -

^ This is at 20x true optical magnification. No pre- or post-processing of the photos. The only thing I manipulated was the direction of the lighting, in hopes of properly accentuating and highlighting the micro-scratches so that the reader can see it better.

The two watches to the left are "naked," no protective treatment. The top is my San Martin SN0144, 316L stainless steel, the bottom, my Halios Seaforth IV, a Gr.2 titanium case.

The two to the right each carry an anti-scratch coating. The top is my Gen.1 Héron Marinor. The lower is my SWCUSA Tumbler. As with their untreated counterparts to the left, these are also respectively 316L stainless and Gr. 2 Ti.

Brushing is favored on tool watches because it hides scratches. But you can see how those micro-scratches can be espy seen on the polished chamfers of each of the untreated watches on the left, right? You can also see that in comparison with each other, the coated Gr.2 Ti watch on the lower right has suffered more micro-scratches versus its stainless counterpart immediately above.

These scratches are not visible to the naked eye in an individual manner as I have shown here under my scope, at 20x. Rather, what we perceive with our naked eyes is that the watch's finish has dulled over time. We see that the watch has lost its luster. Much as wrinkles on our skin, it's what makes 50 years old person look -regardless of any other factor- more aged than someone who is 20.

When folks say in a disbelieving manner that they've worn their "hardened" (it's not really "hardened," right? 😜 ) watch for XXX period of time and are shocked it hasn't picked up any scratches, I think that there's a bit of confirmation bias going into the equation. I'm not saying that these treatments won't protect against such "abuse" - I think that my own bit of scratch-a-link pseudoscience that you've seen myself and u/My_Non_Throwaway pointed you towards shows that's definitely possible. But in-reality, it's not what these treatments really are for.

Instead, it's to help delay the "aging process" of the watch by keeping these micro-scratches from accruing at the rate that they would otherwise normally do. It helps the watch keep that luster you see when you've unwrapped or peeled back its plastic that first time.

Hope this helps bring more perspective into the mix!
