About this entry

60% of key specs known. Missing: lug-to-lug, lug width, weight, hardening, AR coating, crown.

Undone's Aquadeep-style dive case in forged carbon, sold as the Aqua Carbon Maggy, a limited edition made with the manta-ray charity The Manta Trust (listed June 2025; no number of pieces given; "a portion of every Aqua Carbon Maggy sold" goes to the charity). Recorded apart from the titanium Aquadeep because of the case material. Spec table: Japanese TMI NH35A, forged carbon case, double-dome sapphire crystal, 43mm excluding the crown (51mm including crown and crown guard, the same figures as the titanium Aquadeep), 16.5mm including the crystal, 30 ATM / 300m. Undone notes that each case has its own vein pattern and that the material "benefits from mindful care, avoid impacts". The description adds a wave-pattern dial with UV-reactive lume that reveals a hidden manta motif and a rotor shaped like manta wings; the photos show no date window and a see-through caseback. The listing price includes the collaboration box (manta ray pin, sticker, UV flashlight, thank-you and warranty cards); it is made to order, with no returns or discount codes. No lug-to-lug, lug width, weight or crown details are published. Sold out on 2026-10-30. Editions. Maggy (COL-AQD-MAT, USD 680; UNDONE x The Manta Trust): forged carbon case and bezel, black wave dial with blue accents, black fabric strap with blue stitching.
