About this entry
87% of key specs known. Missing: weight, hardening.
The brand's second series (December 2025), on a 38mm case that Oracle of Time says is identical to the debut KTL limited edition but with a push-pull crown instead of a screw-down one. Brand specs: regulated Miyota 9039 (no accuracy figures given), sapphire with inner AR, 316L steel, push-pull crown, 100m, 38mm, 9.5mm thick (the brand does not say whether the crystal is included; its KUBO page states case and with-crystal figures separately, so 9.5mm is taken as the total), 46mm lug-to-lug, Italian calf strap 20-16mm with quick-release bars. Caseback attachment inferred: the product pages show the same caseback photo as the Mune, which Fratello describes as screw-in. Lume compound not named; the brand says the hands and the 12 o'clock triangle glow blue. Ships on the strap only; the Flat Link Bracelet (BR01, ¥26,400, 20mm, quick-release) is sold separately, so bracelet is recorded as not offered. Sold in pre-order rounds: both colourways were sold out on 2026-10-25 with the next reservations opening in early December 2026 for delivery in late January 2027. Reviewers quoted US$690 excluding tax.
