Known for its reliability, it was a staple engine behind some of the brand's most iconic vintage watch lines, including the Enicar Ultrasonic and Seapearl series.
Movement Type: Mechanical, manual-wind Dimensions: 11.5 ligne (25.9 mm diameter) x 4.20 mm height. Frequency: 18,000 beats per hour (bph) / vibrations per hour (vph)
Power Reserve: Approximately 42 hoursJewel Count: Available in variants with 17, 21, or 25 jewels Functions: 3 hands (central sweep second hand, hours, and minutes)
Escapement: Swiss lever escapement. Shock Protection: Incabloc mechanismMovement Family: Belongs to the broader Enicar series that includes the 980, 1009, and 1011 familiesHistorical Context & Collectibility.The Caliber 1010 was an instrumental workhorse during Enicar's golden era of manufacturing.It was frequently paired with historically significant watch cases, such as the water-resistant EPSA-STOP and compressor cases used for early ocean-faring watches.Some high-grade versions of the Cal. 1010 were even tuned to meet strict chronometer certification standards.The code 100/96 BaS stamped on the case back is a specific reference and configuration code used by Enicar in the late 1950s and early 1960s.Here is exactly how to decode it according to Enicar's archival reference systems:1. The Model Reference: 100/96100: Indicates that the watch is powered by an in-house manual-wind movement, which corresponds directly to the Enicar Caliber 1010 (AR 1010) movement.96:This is the specific dial and case design layout variation within that model line.This design profile was used primarily between 1957 and 1960.2. The Configuration Code: BaSEnicar used a letter-based coding system to describe the watch's construction and features:B: Stands for Seapearl case.This means the watch uses the famous water-resistant bayonet-closure case back engineered by case manufacturer EPSA (Ervin Piquerez S.A.).a: Stands for All Stainless Steel (a lowercase "a" indicates the case material is completely steel, as opposed to gold-plated).S: Stands for Sweep Second. This confirms the movement has a central, sweeping second hand rather than a sub-dial.
