Rotary Watches Ltd. (founded in 1895) was widely recognized by its logo, a “Winged Wheel”. This is a symbol often associated with the Ancient Greeks, specifically the Greek god Hermes. It was considered to be a symbol of movement & progress, two concepts that mirrored Rotary’s values. The brand shared a strong connection with the UK market, including being headquartered there, and in 1940 was awarded a contract from the British government to be a supplier of field watches for the army.
By the 1960’s, Rotary became more well known for producing Dive watches, including the “Aquaplunge” Diver (666/ft) and “Aquaplunge” chronograph. Featured here is a late 1960’s Rotary Aquaplunge Super Waterproof Diver Ref. 66.18.59 - Powered by a 21j automatic AS Cal. 1700/01. Among its notable features is a beautiful 12h/24h black dial laid out in perfect symmetry with the logo and other dial info. Earlier models may feature the “Rotomatic” designation (vs. Automatic), a 17j or 21j AS Cal. 1700/01, Broad Arrow Hands, and Radium and/or Tritium dials.
Finding these tool watches in nice overall condition can be a challenge. They were used as intended back in the day. But if you do, they are worth snatching up! Aside from this Ref. 66.18.59, older References include Ref. 80.18.32 & Ref. 81.18.54. They are wonderful pieces at 36mm, with tons of character, wrist presence, and a great history to boot!
