Description
The Amsterdam-based independent Maen has refreshed one of its best-known models with the Hudson 38 GMT MkII, the second generation of its 38 mm compact caller GMT. The MkII keeps the case size that made the original work — true 38 mm, 11 mm thick — and tightens almost everything around it: sharper case finishing, drilled lugs, a screw-down crown, an elaborated-grade Sellita movement, and a new on-the-fly micro-adjustment clasp on the bracelet.
Pre-orders open on 20 May 2026 at EUR 1,249 for the head-only version. After 24 May the price rises by EUR 100; deliveries are scheduled to start in December 2026. The watch is offered in two bezel configurations — a warmer brown-and-black and a subtler blue-and-black — and is sold direct from maenwatches.com.
Design
The case is brushed across the mid-case and lug tops with polished bevels running along the lug edges; the brushing on the MkII is visibly more uniform and sharper than on the original Hudson GMT. Drilled lug holes reinforce the watch's utilitarian-tool intent and make strap changes easier. The screw-down crown is signed, and a solid screw-down case-back supports the 300 m water-resistance claim. The bezel is bidirectional, with a 24-hour scale executed in either the brown/black or blue/black palette and a luminous pip at zero.
The dial is matte black with applied indexes, generous Super-LumiNova in both the indexes and the GMT hand, a peripheral 24-hour scale on the rehaut, and a date window at 3 o'clock. The GMT hand is colour-matched to the bezel — orange-brown on the brown variant and red-orange on the blue. The handset is a vintage-inflected sword-and-arrow pairing on a clean dial layout that errs toward legibility rather than ornament.

What's Exciting
Caller GMTs at this price point are a crowded segment now, dominated by the Miyota 9075 and the Sellita SW330-1. Maen has gone a step up in two specific places that genuinely matter. First, the movement is the SW330-2 in Elaboré grade — a higher specification of regulation and finishing than the SW330-1 used in most competitors, and a small but meaningful step over the SW330-2 Standard grade. Second, the on-the-fly micro-adjustment clasp is still rare at sub-EUR-1,500; pairing it with quick-release end-links makes day-to-day strap and fit changes meaningfully easier on the wrist than most peers.
The 38 mm × 11 mm thin-for-300 m proportions are also best-in-class for a true dive-grade compact GMT, and the brown-and-black colourway in particular has a vintage-tool feel that the more obvious Coke and Pepsi pieces in this segment don't get to.
History
Maen was founded in Amsterdam in 2014 by Christophe Hoppe with the brief of building well-proportioned, well-specified microbrand watches with a clearly Dutch-Modernist design sensibility. The Hudson line started as a 38 mm dive watch and added a GMT variant in 2022 — the Hudson 38 GMT MkI — which used the Sellita SW330-1 caller calibre and earned a strong reputation for proportion and value. The MkII keeps the chassis but resolves the small irritations of the original: clasp adjustment, movement grade, lug finishing.
The Hudson 38 GMT MkII also lands inside a broader 2026 shift in the microbrand caller-GMT segment toward Elaboré-grade Sellita movements and on-the-fly clasps as standard, rather than upgrades. Maen's pricing and feature combination are consistent with that direction.
