NOTES:

The marking HB-1085 (found on a small plate attached to the side of the case) is a design detail that references Swiss civil aviation registration codes.

Meaning of the Code

HB (Hotel Bravo): This is the international radio call sign and two-letter registration prefix assigned to all aircraft registered in Switzerland

The Number (1085): While real aircraft use letters (e.g., HB-JNI), Zenith uses a numeric figure on this plate to represent the specific individual series number of the watch. Each plate is unique to that particular timepiece, mimicking the look of a registration plate found in civil airplane cockpits.
