The architecture of Cal. 360 is disputed. Christie's describes a 1938 ref. 2835 "Prince Elegant" with a tonneau-shaped 15-jewel movement, and Charles Jarman's ''The Rolex Reference Guide'' (4th edition) calls Cal. 360 a manual, small-seconds, tonneau-shaped movement with a SuperBalance. Watch Doctor’s online chart instead lists a rectangular, 18-jewel movement measuring 18 × 27mm. The page does not identify an underlying Rolex document.

Jarman dates Cal. 360 to 1937. The expansion of the HW designation remains unconfirmed; it should be retained as a designation rather than expanded to Hans Wilsdorf. The differing shape and jewel descriptions need comparison with the movement in the individual watch.

The differing shape and jewel descriptions need comparison with the movement in the individual watch. Ineichen’s 2016 catalogue attributes C.360 to a Prince ref. 1880 and describes a nickel-plated lever movement. That is one lot-level attribution; it does not resolve the conflicting descriptions above.
