The **Pilot's Watch Ref. 104** is [[pilot's watch]] by [[Sinn]] from [[2013]] to present.

===== Overview =====
Sinn calls this model "Die klassische Fliegeruhr" (The classic aviator watch). It is an affordible three-hand watch, which is also suitable as an entry model to the world of mechanical watches with [[self-winding]] movements. The Sinn 104 has a practical bidirectional rotating bezel, numbered counter-clockwise with 60 markings. It also shows the day and date in a window at 3 00. Through the caseback with [[sapphire crystal]] the movement can be observed.

The 41 mm case is similar to the one used on the [[Sinn EZM 3]] and the case and bezel were adopted for the follow-on [[Sinn EZM 3F]].
