The **TAG Heuer Calibre 1887** is an automatic chronograph movement from [[TAG Heuer]]. In [[2015]], this calibre was re-branded **Heuer 01**.

The 1887 is a mechanical [[chronograph]] calibre with [[self-winding]]. It was developed by TAG Heuer, based on the calibre platform TC78 ([[1997]]) from Seiko ([[Seiko 6S37]]). In [[2006]] the rights for exclusive production in Europe were purchased from TAG Heuer. The movement is completely manufactured in-house and is somewhat different in design from the Seiko base. The 1887 includes a larger 29.3 mm plate and is thinner overall. It was designed for additional complications, including [[power reserve]] and [[retrograde]].

The first models with this calibre are 

  * [[TAG Heuer Carrera 1887 Chronograph]] ([[Baselworld]] 2010)
  * [[TAG Heuer 300 SLR Calibre 1887 Chronograph]] ([[2010]])
