'Tropical' watch dials gained traction in 2000s. They can be recognised by a "brownish" hue which is a result of excessive sun exposure coupled with the lack of manufacture paints available at the time that were UV resistant. Nivada Grenchen has taken this aesthetic and applied it to the iconic Chronograph Aviator Sea Diver Broad Arrow. They have take the vintage styling a step further by coating the handsets and indices in artificial patina or "fauxtina". Powered by the Sellita SW510 M BH b, the wearer of this watch can enjoy 63 hours of power reserve with this modern and reliable movement.
