Moon-phase version of the Helica in the 39mm case, listed by Zelos on 11 January 2026 (sales opened 15 January per Gear Patrol) in three versions. All three were sold out on 2026-10-21 and none has been restocked; Zelos still lists them in its Helica collection, not in Discontinued Models, so the model is recorded as limited. Edition size: Gear Patrol says "Each of the three versions is limited to just 100 examples", and Zelos's caseback photo is engraved "016/100"; Zelos's own text gives no number. Movement: Zelos says "Swiss Sellita SW288 'Panoramic' Moonphase, Manual Wind"; the movement photo shows the plate engraved "SW 288-1" and the bridge "Eighteen (18) jewels" with no rotor, which matches Sellita's hand-wound SW288-1 M (18 jewels) rather than the 26-jewel automatic SW288-1; grade not stated. The moon phase is a large aventurine disc seen through a smoked sapphire aperture in the upper dial, with the date at 6 (photos). Zelos spec list: 39mm, 45.5mm lug to lug, "10mm without crystal, 11.9mm with crystal", 316L steel with brushed and polished surfaces, 20mm lugs, 100m, box-shaped sapphire with inner AR coating and a sapphire caseback, Lumicast BGW9 indices and a BGW9-lumed moon phase, multi-link faceted bracelet with quick adjust clasp tapering 20 to 16mm. Gear Patrol: the front crystal is a near-2mm-high box sapphire; both moons, the hands and the two-piece applied indices (solid Lumicast blocks) carry Super-LumiNova X1 BGW9; the bracelet has quick-release spring bars and a micro-adjustable clasp "activated by pressing the Zelos logo button on the outside", recorded as on-the-fly because Zelos describes its external-button quick adjust as making adjustments "without having to undo the clasp" (Swordfish page); positions not stated for this model. Fixed steel bezel and solid end links per SeriousWatches. Five links per row counted from Zelos's photos. Crown type not stated. Gear Patrol gave the price at launch as $949 (not broken down by version); the store now lists $1,049 (Aventurine, Mosaic MOP) and $1,099 (Meteorite). Weight not published.
