Short overview, not a review. Pros and cons restate published facts only. No buying advice. Numbers not shown on a source we opened are omitted or marked unpublished.
Citizen’s Japan-market The Citizen line adds a Tosa washi dial limited reference AQ4100-65X. The domestic shop lists reference values for 38.3 mm horizontal case width (excluding the crown and crown guard), 12.2 mm thickness, and 82 g weight; 10気圧防水 on the shop copy; movement Cal. A060 at ±5 seconds a year; world limited 300 pieces; and ¥440,000 tax-included (¥400,000 excluding tax). Japan shop copy schedules release for 8 October 2026 (発売予定 — not a settled on-sale date). Citizen Watch Global’s 17 September 2026 news lists 10 BAR water resistance, schedules an October 2026 launch, and projects USD 3,000; it describes 38.3 mm by 12.2 mm as a design specification only — separate from the Japan shop’s reference dimensions.
