Seiko Flightmaster Pilot Slide Rule Chronograph SND255 SND255P1 SND255P Men’s Watch

A sophisticated piece of scientific art to mark unusual and ambitious achievements while in air. The highlight of the high-end Seiko Prospex Flightmaster is its shining, deep blue, bidirectional timing/compass bezel and dial. This is a rare bird even in the Seiko chronograph range for its rotary slide rule that makes rapid calculations and conversions possible for a large range of fight data, including flight speed and fuel consumption rates.
