I have taken a few modern watches into Swisstec/STS and the service has been good so when I bought a Speedsonic on Ebay with butchered hands I took it there as well.
Simon informed me that they had already serviced it this year (2016) so only charged for the repair.
Unfortunately it took them a long time to get the hands right and then found that the chronograph did not work properly when checking after the work so they serviced it (FOC).
Although it took some time, the results were worth it and Simon was really helpful as always.
I also managed to obtain the correct bracelet for the Lobster, before and after pics below.
