A stunning and functional objet d'art, The Erwin Sattler Longcase Clock – Troja 16 M would be a treasured gift for any watch collector. Known for their high precision of movement, pieces by the Munich-based, family-owned company are rarely available at auction. They can only produce 5 or 6 watch winders, such as this one, a year due to their complexity. Made in the early 2000s, this particular example features 16 extendable, individually programmable watch winders, in addition to its pendulum clock. Ahead, Sotheby’s selected 16 exceptional automatic timepieces from upcoming sales that are as striking on the wrist as on this Erwin Sattler watch winder.
