Across the 4 Citizen models with standard lugs in our index, lug widths are 18mm (1), 20mm (2), 22mm (1). The most common is 20mm, but don't assume: sizes vary within the brand, so check your exact model below. the Tsuyosa uses an integrated or proprietary fitting, so normal straps need an adapter (how that works).
