It had taken me a really long time to get a German watch I wanted to keep and as my favourite AD had this in I thought that I should give it a go as I was also wanting a white dial gmt and this one looked great. 

 

Positive Points 

Tool watch lovers (and I count myself as one of them) will love this watch. It's incredibly legible, possibly the most legible watch in my collection, and that includes during the first bit of darkness as the lume is very well applied.  The dark blasted steel case and black 24hr rotating gmt bezel will take scratches so much better than a shinier case such as the one that came with the limited edition Seiko Alpinist GMT that came out in 2024. Also while some may consider a 41mm case at the larger end, and the lug to lug of 48mm and thickness of 12mm while not over the top won't make these people any happier but the case construction especially in regards to the lugs allows the watch to hug the wrist really well. 
The orange utc hand and text add a splash of colour to what some might consider a plain white dial. 
The movement is a common Sellita one, but that shouldn't put people off as it's a very serviceable one with a 56hr power reserve and a beat rate of 28800bph and is just about right at this price point. And it looks pretty good to. 

 

Negative Issues 

The dial is a very plain looking one, and there are many other watches at this price point that will do interesting things with their dials, while this is just a clean matte white dial, which is great for visibility but may be considered dull for some, particularly if the tool watch aesthetic isn't for you. 
Sinn bracelets generate mixed reviews with people. The resizing system requires the use of two Allen keys that come with it, and misplacing one of these would be an annoyance. Also the lack of a quick release system with a watch at this price seems a little ridiculous and no toolless micro adjust either, which is pretty much standard now. 

 

Conclusion

So this isn't a watch for lovers of dress watches or intricate dials, however if that's you than you're probably not looking at this anyway. Also the bracelet issues may seem like an annoyance to many, it doesn't bother me too much but I understand why people don't like it. 
All in all though I really like this watch, I think the dial looks crisp and clean with the touches of orange stopping it from being boring. I bought this through an AD and I have heard some people have had issues dealing with Sinn's customer service, but the watch is a definite yes for me.
