Regulated my 80188 Laureato quartz
Recently acquired an 80188 like @SingaporeMarc
After enjoying it for about a month, I found that it was running a bit slow. Probably due to the warmer climate here.
Therefore, after taking a deep breath, I opened the caseback and regulated the cal. 13500 using (what I guessed to be) the trimmer screw (in red circle).
I can now confirm that counterclockwise=faster, hence the arrow engraving.
After regulation: gaining around 0.044 s/day, unworn
Wearing it will tend to slow it down, therefore even closer to the zero average rate.

Brilliantly brave of you 😮
Glad to see another 80188 with an avid collector. This information of regulation will be of benefit to many to appreciate the difference between a high-quartz and the more pedestrian types. Just like mechanical, there is a range and GP was the original Sw...
