Deniss Fedotovs, 26.08.2025., 11:50Rolex Spare Parts Catalogue got published in 1948. It includes parts lists for following calibers: Rolex 90, 100, 150, 160, 161, 170, 180, 200, 210, 250, 270, 300, 310, 350, 360, 400, 420, 500, 510, 520, 530, 600, 620, 630, 700, 710, 720, 730, 740, 800, 850.

Spiral bound, plastic covers with guilt letters. Around 100 pages total, including some pages advertising Rolex watchmaking tools.

All these calibers were manufactured by other companies - the first Rolex in-house caliber was made in 1957 only.
Around 1960 the Rolex Spare Parts Catalogue Vol. II was published which included also some Tudor watch calibers.
Later the Rolex Spare Parts Catalogue Vol. III was also published with Tudor watch calibers included.
Update on 30.11.2025: The publishing data has been narrowed down from 1945-1950 to the end of 1948 as in March of 1948 Rolex Spare Parts Provisional Catalogue was published with the same calibers, saying that "we shall publish General Catalogue of Rolex Watch Materials in the course of 1948".
Information about all watch calibers represented in this catalogue can be already be found in The Watchmakers App, which has the most comprehensive Rolex movements list to this day.
