====== R150 ====== Calibre **R150** is an [[automatic]] watch movement made by [[Ronda]] and introduced in [[2016]]. Ronda was best-known for [[quartz movement]]s, but the decline of movements and [[ebauche]]s from [[ETA]] in the 2010's led the company to introduce an all-new mechanical movement. Cal. R150 is designed as a drop-in replacement for ETA's mainstream three-handed [[2824]] movement, and as such includes the same dimensions and mounting points. Design of the R150 began in [[2011]] just as [[Comco]] announced that [[Swatch Group]] could decrease movement supplies. Cal. R150 will meet the requirements to be called [[Swiss Made]] even though some components are sourced from Ronda's existing factory in [[Thailand]]. The balance spring is supplied by [[Carl Haas]] of Switzerland. Cal. R150 operates at 28,800 A/h like Cal. 2824. It measures 11.5 [[ligne]]s (26 mm) and is 4.4 mm thick, 0.2 mm less than Cal. 2824. Power reserve is 40 hours. {{tag>Movements Ronda_calibres Automatic_movements}}
