	Price anchoring. The indexed market runs roughly $1,300–$3,500 for standard configurations, higher for California dials and Kew A examples. The Bonhams £1,152 result sits in the middle of that. A 4220 priced above $5,000 wants an exceptional California dial, Kew A provenance, or some other specific lever; a plain 4220 at five figures is out of step with the surfaced record.

	The 4220 is the centre-seconds Speedking of the 1940s: a 30mm stainless steel Oyster, Mercedes hands at the centre, and on its first-half dials a California "Error-Proof" layout, Roman numerals across the upper half and Arabics across the lower. The California was a Rolex patent, filed 30 May 1941 and granted 15 June 1942. The 4220 arrived alongside it. Bubbleback ref 3595 carries the same dial on the Perpetual side; the 4220 is the Precision-line counterpart and, for most 1940s-oriented collectors, the reference the Speedking name points at first.
