Here we have a beautifully appointed 1960 JLC Memovox Worldtimer Bumper Auto Cal. 825. Introduced in 1950, it was originally called the “Wrist Alarm” but was later changed to “Memovox” for the 1950 Basel watch fair. The name in Latin means “Memor” (Remember) and “Vox” (Memory), a clever play on words. It was a direct competitor of the 1949 Vulcain Cricket Alarm, and it was famously given to Charlie Chaplin in 1953 to celebrate his arrival in Switzerland. A 36.5mm stainless steel round case sits comfortably on your wrist thanks to the tapered, angled lugs, and the curved flanks lead to a lug-to-lug length of 45mm and a case thickness of 13mm. On the right side, we have a coin-edge signed crown at two o’clock to rotate the alarm disc and wind the alarm and a coin-edged signed crown at four o'clock to adjust the time. A smooth bezel holds a domed crystal above a cream and silver domed dial. Applied polished steel baton indexes mark the hours surrounding an inner minute track with Tritium pips at the hour. The inner rotating disc incorporates a ring of worldtimer cities and an Alarm with a helpful arrow showing where it is set; steel Dauphine's hands filled with lume are complemented by a tapered second hand. At 3 o’clock we have a date window. At 12 o’clock, we have the JLC motif “Automatic” printed underneath, completing this striking Worldtimer Alarm timepiece. On the reverse, a screw-down case back, inside a bumper automatic JLC Cal. K825, 17 jewels, beating at a leisurely 18,000 beats per hour, the alarm hammer makes a distinctive buzzing sound. It comes paired with a suitable 18mm leather strap and pin buckle.
