Hi,
I just added a Sinn 103 St to my lonely U1. I noticed that the bezel is bi-directional and does not have any hatch-clicks at all during rotation. So, it can be rotated smoothly and still holds enough friction against unwanted movement. Is this how it is for all Sinn 103s ?

The local Sinn AD sales person told me that I can actually have the bezel retro-fitted with a ring plate for the hatch-click stops. Has anyone done any mods here ? Just curious to know.

I attached a pic of my 103.

Thanks for your comments.

The clickable, mono-direcional bezel was originally invented for dive watches; the bi-directional friction bezel has been traditionally used for aviation watches. The 103, being an aviation chronograph, is well suited by the latter, I think.

Jimmy,

To my knowledge, all 103s have the bi-directional, non-ratcheting bezel.

i'd love to get my 103 fitted with one of these plates, let us know if you go ahead with it,

Cheers! Ric

Thanks , Martin. That explains the design intent of this Pilot Chronograph.

Hi Ric, I managed to pop out the bezel ........

.... to take a closer look at what's underneath. Basically nothing except some wire-strand that snap the bezel onto case snugly. Yes, I will let you know when I decide to go for the mod.

Love my Sinn St Sa. But like you, I think a bi-directional bezel with a positive 60 click increment would be a nice modification.

Please keep us informed on this. The ONLY thing I do not love about my 103 is the tendency of the bezel to move several minutes one way or the other during the course of a day. Perhaps my bezel is "looser" than most, but it's a rare day that it stays put.
Due to this, I can never trust my bezel to measure any timed event with any degree of accuracy.
