Citizen’s model numbering system is logical but not immediately intuitive. A genuine Citizen model number, such as “BN0150-28E,” breaks down into a movement/collection code (BN) followed by a variant number (0150) and a dash with a band/case finish code (28E for black polyurethane strap). The string “GN-4W-S-12G” does not follow this pattern. The “GN” prefix is unusual; “4W” might suggest a 4-hand watch (hour, minute, second, 24-hour), but “S-12G” has no parallel.
