Limited special editions
The Sinn UTC and the Sinn B are two special editions of the pilot's watch with limited quantities. While their functionality is fully in keeping with the 856 watch series and is in no way inferior in terms of robustness and technology, the editions differ selectively in design and function. The Sinn B, for example, is limited to a total of 856 pieces and is suitable as an observation watch, especially for military purposes. Inspired by watchmaker John Harrison, this model is entirely in keeping with English tradition and is characterised by its deliberately withdrawn hour hand. Clear readability is always guaranteed, even in difficult lighting conditions such as darkness or fog.
