So I have been wearing mine on a custom ziczac for a couple of weeks with a deployant from the GF ultra thin. The stock strap was not wearable. In fact, I’m pretty sure the deployant I received was constructed incorrectly, because it did not come on the strap from the TD and I can’t get it to fit on the strap, so it’s basically garbage.
Strap issues aside, the watch itself is absolutely gorgeous. I have minor issues with the fact that the 2nd time zone hands are not meaningfully different from one another in length, making it hard to read, but everything else is great. There is also the typical miyota loudness. It is quieter than my ZF Calatrava and louder than my GF MUT moon. YMMV.
With regard to the functionality, I will say that this is the best time keeping rep In my collection. It is 5 seconds fast per day on a winder. I am not sure how power efficient it is, though. The reserve drops over time even at 2000 turns per day.
The second time zone functions somewhat strangely but it does work. Going forward the time on both dial and subdial changes. Going backwards, only the minute hand changes, which allows you to set the subdial hour independently. There is a sight issue with the alignment of my subdial minute hand; it is slightly out of sync with the main minute hand, but not a big deal.
Overall, I’m very happy with my purchase. I think the watch looks and feels great and it is well made. As I mentioned, I have some minor issues with various aspects but nothing that would keep me from loving it.
