How thick is the case?

UN Sonata

First generation with closed case back, my favorite of all the Sonata releases. What a technical masterpiece! The case design is still unique as it was when first released. Technical prowess with off-beat design charm. 17 years young and counting.! ...

UN Sonata

Very appealing indeed.

One of the most exciting UN watches of all time 🙌🏻👏🏻👌🏻

I have the very same one, and it is one of those which are very dear to my heart.

How thick is the case?

~13mm

Yep.

The Sonata is one of the brand's best. I love the hands especially.

Agreed!

Such a great UN.

All time best alarm watch that’s also probably the best travel watch. I prefer Sonata Cathedral as the alarm sounds a bit louder. In fact I traded my original for the Cathedral when it was first released.

Wonderful! I don’t know the cathedral was louder.

I confirm. Louder, but less " round " or " sweet ", too.

Would like to have a side to side comparison. Regardless, either model is an incredible mechanical marvel.

Agreed. I could do so because I had mine when I discovered the Cathedral.

Same but it was soling ago and I can’t remember yesterday. So now it’s pure speculation unless someone has both. 🤔

Well, when we meet, we'll do it. ;)

Absolutely masterpiece even after 17 years

My opinion on the..

I know you are a fan. ;)

Yes, just not...

So you saw the watch and one of its creators? Wow!
