Reference 3646 is exact, but it spans several wartime types and movement/dial configurations. The measured 47 mm value applies to the cushion case, not a universal complete-watch silhouette. Dimensions in this record are specimen-specific source claims, not one combined physical watch: the 54 mm lug-inclusive span applies only to Type D case 260563, while the 15 mm and 16 mm heights describe separate cases 1010260 and 260429.
