The Enicar 1010 (designated as AR1010) is a vintage, in-house, manual-wind mechanical watch movement manufactured by the Swiss horological firm Enicar. Introduced in the 1950s, it represents one of the brand's earliest generations of in-house movements, predating the widely known 1120 calibre family. In July 1954, the AR 1010 achieved a major milestone for the brand when it was officially accredited chronometer status by the Neuchâtel Observatory.
