At 29.4 mm, the A&S1612 movement is designed to fit a 38 mm diameter case that is just 10.44 mm thick. This manually wound movement, with an autonomy of 90 hours, perpetuates the range of Arnold & Son calibres with impressive power reserves. Staying true to its tradition as a watchmaker that values accuracy and its legacy of high-sea navigation, Arnold & Son has ensured that this moon-phase timepiece will remain accurate for 122 years. Thus, when kept constantly wound, it would take over a century for the moon on the timepiece to experience a time lag with its real-life counterpart in the sky.
