Founded in Neuchâtel, Switzerland in 1856, the Ernest Borel Watch Company has long been associated with unique watch designs, including its famous “Cocktail” kaleidoscope dial series. In 1975 the company was purchased by the Synchron Group, its mechanisms and winding crowns stamped with the Synchron logo.

         I am pleased to offer for sale the following men’s timepiece from Ernest Borel, dating to ca 1978 and a lesser seen Conquistador (conqueror) model. This is a quick-change, double date model with a distinctive blue dial and 17 jewel automatic wind mechanism, the first time I’ve seen or owned this model.

          Quadruple-signed, it measures 39.5mm lug tip to lug tip and 35mm in width (37.5mm with signed Synchron crown). It is powered by its original 17 jewel automatic Synchron “5 o’5” mechanism, recently serviced to ensure it winds and sets smoothly while keeping accurate time.

          The sky blue enamel finished dial is 100% original and in excellent shape. It features a 60 second outer track, applied silver hour markers (small age mark near the 9), silver steel hands, sweep center seconds hand and a quick-change double date window featuring a black day of week and red calendar number. Signed Ernest Borel by Synchron below the 12 marker and Conquistador Automatic above the 6 marker. It is further signed Swiss Made at the base.

         The original armored acrylic crystal is in excellent shape. The brushed finish stainless steel case has polished sides and is in spotless condition, as is the winding/setting crown that is signed with the Synchron trademark.

          Looking at the back lid I see that it is a screw-down design stamped Stainless Steel, Automatic, Water Resistant. Also notice that it’s signed “Vitalis U.S. Olymp[ic] Invit[ational] – 1500m Second, 1978.” This suggests that the athlete it was presented to may have also competed in the Olympics at a later date but I don’t know his name.

          Peeking inside I find a clean rotor automatic mechanism signed Synchron 5 o’5 Seventeen 17 Jewels. This is a caliber A.S. 2066 as stamped below the balance wheel, made by Schild from 1969 to 1978 and very popular. The inside case lid is signed SYNCHRON S.A..         This watch winds and sets smoothly while keeping accurate time. To set the date(s) you pull the crown out to the FIRST position and then turn it either forward or backwards to change the day or date. To set the time you pull the crown out to the SECOND position.

          This watch is fitted on a new dark navy blue leather DeBeer watch strap with contrast stitching and stainless buckle. It works nicely with the blue dial but if you prefer a black band I can do that too. Thanks for taking the time to view this very cool, well made and original Swiss Borel!
