UNIMATIC and E. Marinella produce the U4-GMT-EMJDM: 100 numbered pieces in a 40mm steel case with NH34A GMT movement. Available via E. Marinella Tokyo and Floens.
What Sets It Apart
- Limits of 100 individually numbered pieces and a dedicated E. Marinella ties caseback position this as one of the more precisely constrained Italian design collaborations in the Modello Quattro line.
- The NH34A GMT calibre provides a second time zone within a 40mm brushed 316L stainless steel case rated to 300m water resistance.
- E. Marinella’s signature blue and sartorial codes are translated directly onto the dial architecture rather than applied as surface decoration.
- Availability is tightly controlled: selected E. Marinella stores in Tokyo and online via Floens only, with no international shipping.
Design & Mechanics
Milan-based UNIMATIC and the Neapolitan tie house E. Marinella share a common point of reference: Italian design reduced to its necessary elements. The U4-GMT-EMJDM places that shared conviction inside the Modello Quattro, a case architecture already established for its minimal surface treatment and functional clarity. At 40mm in brushed 316L stainless steel, the case carries no superfluous geometry. The blue drawn from E. Marinella’s textile tradition disciplines the dial, while the dedicated E. Marinella ties caseback extends the collaboration to a surface most wearers alone will see — which is precisely the kind of considered detail that attracts collectors to numbered editions of this scale.
Movement & Materials
The NH34A automatic GMT calibre is a practical choice at this price tier: it offers a bidirectional GMT hand set independently from the local hour, reliable self-winding, and a proven service record. Paired with 300m water resistance in a case of this size, the U4-GMT-EMJDM functions as a working GMT rather than a display piece. The brushed finish on the 316L case is consistent with UNIMATIC’s wider production philosophy, where surface treatment is uniform and light reflection is kept subdued.
Market Position
A run of 100 individually numbered pieces positions the U4-GMT-EMJDM well within the territory that attracts focused collectors: rare enough to carry meaning, not so scarce as to be inaccessible on release day. The distribution model reinforces that positioning. Routing sales through selected E. Marinella stores in Tokyo and online via Floens, with no international shipping, concentrates availability and limits grey-market arbitrage. For buyers in the Gulf seeking this reference, the Floens online channel is the most direct route, subject to the stated shipping restrictions.
