According to the Archives of Montres Omega, the present watch, a reference CK 2041 model introduced into the market in 1938, was manufactured with the "St. Christopher" dial. The movement originally made for this case however bears a different number and has therefore been replaced with the present one to a later date.
Two versions of reference CK 2041 with St. Christopher dial are described and illustrated in Omega - A Journey Through Time by Marco Richon, p. 513, pl. 2388 and pl. 3584.
