Customer picture of Sinn 104 St Sa I Automatic (41mm) Black Dial / Black Rubber Strap w/Pin Buckle 104.010 BLACK RUBBER This watch has been on my radar for a very long time. After initial anxieties as I've never seen one in person and about price, aluminium bezel, printed indices, will it be the right size for my wrist? these evaporated when I put it on my wrist. My first word was "Wow".

It's a very simple but striking piece that oozes quality and is robustly built. Very legible from any angle. Looks completely at home on my 7.5inch wrist.

The countdown bezel, although aluminium has been executed to a very high standard and makes for a very useful feature.

Very supple and comfortable Sinn embossed silicone strap with Sinn signed buckle. Fantastic accuracy.

Beautifully decorated movement which can be seen through exhibition case.

You can watch all the YouTube review videos praising this watch, but it's not until you get it on your wrist that you can really appreciate it. Will certainly be a keeper. Worth every penny.
