Streamliner Retrograde Seconds

The Streamliner Retrograde Seconds combines the collection’s fluid design with an advanced 30-second retrograde complication. Its 40 mm steel case houses the HMC 252 Manufacture self-winding calibre, featuring a retrograde module developed by Agenhor SA and partially skeletonised bridges.

The movement operates at 21,600 vibrations per hour, with 31 jewels and a minimum three-day power reserve. Its automatic bi-directional pawl winding system and original Straumann® hairspring underline H. Moser & Cie.’s technical expertise, while the anthracite finish and Moser double stripes add visual refinement.

At 6 o’clock, the retrograde mechanism sweeps the seconds hand across its arc before releasing its stored energy and returning instantly to zero, turning precision into movement.
