Technical career and private workshop
The Jeløy label refers to Rasmus Jonassen Sørnes’s personal clockmaking workshop, not an evidenced commercial watch brand. Sørnes was an electrician and radio technician who pursued complex clockmaking alongside his technical employment.
The family-derived biography places his family’s move to Jeløy in 1932 and describes a workshop behind the house; the radio-station move was earlier. The family biography explicitly characterizes these inventions as personal work rather than a mass-production or profit-seeking enterprise. 12
Astronomical clocks and chronology
NBL credits Sørnes with four astronomical clocks and records surviving workshop tools with the Borgarsyssel Museum collection. The first clock’s chronology differs: NBL describes work beginning in 1930 and completion in 1935/36, whereas the family website starts it in 1935.
Clock No. 3 was completed in 1954, combining time and astronomical displays with a mechanism allowing its indications to be advanced or reversed. Clock No. 4 reused the basic gear design of No. 3 in a differently presented clock, according to the family catalogue. 1234
End of making and survival
Sørnes retired from radio employment in 1958 and died at Jeløy on 15 February 1967. The family catalogue associates Clock No. 3 with Borgarsyssel Museum in Sarpsborg; its 2013 storage note is not present-day display confirmation.
This is a notable personal astronomical-clock practice; corporate ownership, a commercial successor and ongoing production cannot be inferred from museum preservation. 213
