Synergies Horlogères is a watch movement maker located in Biel, Switzerland. In 2014, it was merged with English watch brand Christopher Ward with both companies coming under the umbrella of Christopher Ward London Holdings.

Synergies Horlogères, best known for their watch prototyping business, had been purchased by Fossil along with etablisseur Montres Antima SA (founded in 1919) and band and case supplier Meliga Habillement Horloger SA in 2001 and 2002, respectively. It served to design and produce Swiss watches for Fossil, Feldo, Meistersinger, Maranello, Fortis, and Vasto. This Biel-based group, known as Antima under Fossil, was spun out as Synergies Horlogères in 2007. Fossil retained their Basel case manufacturer and headquarters.

In 2014, Synergies Horlogères merged with Christopher Ward. At that same time, Christopher Ward announced their own in-house Calibre SH21, designed by Johannes Jahnke and produced by Synergies Horologères. Today, this movement maker also supplies other watch makers including Meistersinger with various versions of the calibre SH21.

• SH 21 - Double barrel hand winding or automatic movement for Christopher Ward and others.
• MSH 01 - Single-handed hand-winding movement for Meistersinger
