Model 240 is an automatic watch from Sinn produced since 2015.


Introduced at Baselworld in 2015, Model 240 features a similar case to the legendary Model 140 Space Chronograph but with a simpler movement and design. Like its predecessor, it has an inner rotating bezel controlled by a crown, though this is moved from 10 00 to 2 00. The bezel is numbered in 60 increments with numerals at 5 through 55, clockwise. The dial also features day and date windows at 3 00.

The basic Model 240 St was augmented in 2017 with Model 240 St GZ with a tide indicator on the inner bezel. Another special version, Model 240 C, was produced for Chronos magazine in a limited edition of 100 examples. This model features a 12 hour bezel that can be used to show a second timezone.
