The Sinn 156B, particularly notable for its unique Lemania 5100 movement and distinctive orange hands, exemplifies Sinn's commitment to precision and durability in pilot watches, making it a sought-after piece among collectors of aviation timepieces.

Released in the late 1990s, the model's limited production and the exceptional condition—demonstrated by a recent overhaul—enhance its desirability within the collector market.

The watch's rarity is compounded by the diminishing availability of well-maintained examples, particularly those showcasing the sought-after orange chronograph hands.

As a product of German engineering with ties to the military watch tradition, it reflects the meticulous craftsmanship that enthusiasts value, solidifying its standing in the luxury watch community.
