Hi Sam,
The Sinn 358 model was introduced last year. So, there are not many
around for people to show us. I have not seen a real 358 model. The
movement has been used for (I think) about 10 years.
The skeleton UTC hand rotates once in 12 hours, and adjusts without
stopping the movement. I think it is handy for reading UTC. If you don't
want to see it for a while you can hide the UTC hand behind the hour hand,
and it will stay there.
Members "jroof" and "sennheiserz" posted (
there) about their Sinn 358
Jubilaum watches, which use the same domed sapphire crystal. I could
be happy with acrylic, but the sapphire might impart a pleasing color at
certain angles. I don't know. I would like to see it.
In my opinion the grey metallic dial with black sub-dials looks very nice.
It imparts a kind of subtle but eye catching appearance to the dial. The
grey dial is worth checking out. If price is not a primary concern, and a
new watch is ordered I suggest asking about a build with the yellow UTC
hand from the Sinn 103 UTC. That little bit of color would go nicely with
the grey dial. You don't mention your location. A trip to Germany would
let you examine one of these.
If you do get the 358 Diapal please some back and post some photos.
Thanks,
