About this entry
63% of key specs known. Missing: lug-to-lug, weight, hardening, bracelet links, end links, link attachment, clasp micro-adjust.
The no-date Sea Storm, a 38mm skin diver previewed for presale in November 2020; the date version (Miyota 9015) is recorded separately as Sea Storm (Miyota 9015). Two store listings: the "Limited Run Skin Diver" with a 120-click unidirectional bezel (Decimal typeface by Hoefler & Co.) at $690, and a fixed polished-bezel version at $670 (from 2021); the bezel styles are recorded as variants. Brand specs: 316L, 38mm, 11.1mm "without crystal", boxed sapphire with inner AR, 20mm lugs, 150m, signed 7mm screw-down crown, C3 Super-LumiNova on rhodium-plated hands, Miyota 9039 with no date window or ghost position. The 13mm total height is The Time Bum's pre-release figure for the case with its domed crystal. Lug-to-lug left blank: the fixed-bezel listing says 46mm, the skin-diver listing 47mm. Every watch ships with the steel bracelet (butterfly clasp, polished bevels and centre links, hand-brushed links) and a second strap. The Time Bum: 125 of each skin-diver colourway, presale $575 ($300 deposit + $275). The skin-diver listing's photos for Matte Black / Granulated Silver and Storm Gray show a date window (shared with the date listing), so they are not used here. Weight not published. All colourways were sold out in the store data on 2026-10-31, although the fixed-bezel listing text calls Black, Silver and Storm Gray in stock.
