At 36.0mm diameter and 8.7mm thick, this is an exceptionally refined case size for a solar radio watch — a technical achievement given the movement it houses. Powered by Solar Radio Caliber 7B62 with radio correction from Japan, China, USA, Germany and the United Kingdom (five countries — one more than the HAD003J), perpetual calendar to 2099, and approximately 9 months' drive time on a full charge. The Edo Purple dial features the same horizontal pattern emboss and vertical gradient as the HAD003J. Pure titanium case with Dia-Shield coating. Mirror-polished centre bracelet links with gold tone. Super Clear sapphire crystal. \"LIMITED EDITION\" caseback. 10ATM water resistance. Releasing October 9, 2026.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003e*Pre-Order!
