The Kurono Tokyo Grand Jubilee Calendar is a limited-production automatic watch with a triple-calendar display: month, day and date alongside hours, minutes and seconds. Kurono announced it in 2025 to mark Hajime Asaoka’s 60th Diamond Jubilee. Its standout details include a frost-inspired seasonal dial, vertical guilloché and a gold medallion. The announced launch price was US$2,380, excluding VAT and duties; that historical price does not establish current availability or cost.

What does the Grand Jubilee Calendar display?

Kurono calls the watch a triple-calendar complication. It displays the month, day of the week and date, in addition to hours, minutes and seconds. The brand described the release as its definitive complication for the commemorative year in its official product information and launch-video description.

Why is this Kurono release distinctive?

Kurono linked the watch to Hajime Asaoka’s 60th Diamond Jubilee. The brand says its palette draws on red autumn leaves seen through delicate frost columns, a seasonal idea reflected in the dial’s colors and texture. The dial has a delicate vertical guilloché pattern; a gold medallion is engraved with Asaoka’s hanko, and the crown carries a natural black onyx cabochon. Kurono’s launch-video description also calls the hands “onyx-like black.” These are the maker’s descriptions of the design.

What strap fits the watch?

Kurono specifies a 20 mm lug width and a 16 mm buckle width. A replacement strap should therefore be 20 mm at the lugs and compatible with a 16 mm buckle if you plan to reuse the original buckle. Confirm the taper and buckle attachment against the strap and hardware you intend to use; the lug measurement alone does not establish every aspect of fit.

What did the Grand Jubilee Calendar cost?

Kurono’s stated 2025 global launch price was US$2,380, excluding VAT and duties. The brand announced that online ordering would open Friday, October 17, 2025, at 11 PM JST. Those are release-period details, not a current offer. The official materials describe production as very limited but do not give an exact piece count. They do not establish present inventory, resale value, shipping charges, or the taxes and duties a buyer would owe in a particular country. Check the live official listing and applicable checkout terms before treating any price or availability as current.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
