Catalogue description
Dealer description — Craft & Tailored
Many Enicar watches host the word ‘Ultrasonic’ beneath the iconic Saturn logo. Now, while that marker does not indicate a specific reference or style of Enicar, it does in fact bear witness to the manufactural use of a new technological procedure now ubiquitous in the watch world. A procedure that Enicar conceived in 1953 in their factory in Oensingen, a city located in northern Switzerland. The 'Ultrasonic' process was designed by the Federal Institute of Physics in Zurich and was used to clean watch movement parts before assembly using ultrasonic waves. The institute then further enhanced the technology by formulating a special chemical coating, which was applied to each piece of the movement. The coating prevented lubrication from diffusing throughout, which kept the lubrication in its intended locations within the movement. This process added significant lifespan to their watches and minimized the owner's need to seek frequent watch service. This special lubrication process was one of Enicar's prized innovations. Stock # ENUS100107 Brand Enicar Style Ultrasonic Model 100/107 Serial N/A Size Men's Material Chromium Dial Cream Millimeters 36 Bracelet 2pc Handmade Leather Strap CASE & BRACELET The chromium-coated case of this Enicar Ultrasonic measures 36 millimeters and, while well worn, has never been polished. The edges, of which there are many, from the bezel to the case sides and lugs, are sharp and well defined. The bezel and lugs are both beautifully designed, with a wide footprint that gives the 36mm size some definitive visual weight. The Enicar features a screw-down case back and is worn on a gorgeous dark blue leather strap. DIAL & HANDS We could describe any number of dial design elements here as stunning because they all are. From the cream color of its surface to its intoxicating leaf-shaped gold hour markers. From the razor-thin, radium-filled dauphine hands to the statuesque 12-hour numeral. The addition of double bar 6 and 9 markers, as well as the gently curved and bordered red date wheel all coalesce for a simply gorgeous wristwatch that exudes sophistication and style. ACCESSORIES

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide
Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
