The Streamliner Small Seconds Lime Green Enamel Boutique Edition (ref. 6500-1201) demands your attention the moment you set eyes on it. Just announced, this exclusive variant of what collectors have come to regard as one of Moser‘s most refined modern references takes the architectural bones of the 2023 original and rebuilds the entire visual experience around a single, electrifying colour.
Twelve Firings, One Unrepeatable Result
The centrepiece here, as it should be, is the dial. H. Moser & Cie. crafts it in Lime Green fumé Grand Feu enamel over a hammered gold base, and the process behind it deserves careful attention. The master enameller begins by engraving a textured pattern into the gold substrate, then finely crushes three separate colour pigments and washes them onto the surface to create the signature fumé gradient. That application alone takes roughly one hour of focused, unhurried work.
Each round in the furnace causes the pigments to oxidise and fuse together, building depth and translucency without any pixellation. Twelve firings in total bring the dial to its finished state: a surface that shifts from an intense, almost electric green at the periphery toward a luminous, almost golden centre. Discreet applied indices sit at the edge of the dial, and the no-logo policy Moser has held for years keeps the surface entirely clean. Three-dimensional hands carry Globolight® inserts for legibility, and a lacquered sub-dial with a circular pattern at 6 o’clock houses the small seconds in a calm, measured counterpoint to the vivid main dial. Every single dial produced this way differs from the next, which means every watch that leaves the manufacture is, in the strictest sense, unique.
Calibre HMC 500 and the Case for Understatement
Flip the Streamliner over and the partially skeletonised HMC 500 calibre reveals itself through the see-through caseback. H. Moser designed and produced this movement entirely in-house, and at 30.0 mm in diameter and just 4.5 mm tall, it ranks as one of the smallest manufacture calibres Moser has built in the 21st century. The movement runs at 21,600 vibrations per hour, counts 26 jewels, and relies on a solid platinum micro-rotor mounted on ball bearings to wind the mainspring via a bi-directional pawl system.
Platinum’s exceptional density allows the micro-rotor to store and transfer energy efficiently without the bulk of a conventional full rotor, and the result is a minimum power reserve of 74 hours in a case that remains genuinely slim. The finishing tells you exactly where Moser‘s priorities lie: an anthracite grey coating covers the bridges, the Moser double stripes run across the surfaces with a sharp, contemporary regularity, and the H. Moser hallmark appears engraved directly onto the micro-rotor. Nothing shouts. Everything endures. The movement also incorporates an original Straumann® hairspring, produced by Moser’s sister company Precision Engineering AG, which manufactures regulating organs for the brand’s own use as well as for partner companies.
39 mm of Cushion-Shaped Conviction
The case draws its inspiration from the aerodynamic silhouettes of high-speed trains from the 1920s and 1930s, and that heritage translates into a 39 mm cushion shape in brushed and polished steel that looks both modern and deeply considered. At 9.3 mm without the crystal and 10.9 mm with the slightly domed sapphire in place, this is a genuinely slim sports watch. A screw-in crown engraved with the letter ‘M’ and a water resistance rating of 12 ATM complete the practical credentials.
The integrated steel bracelet extends the case’s curves in a way that feels organic rather than engineered, with each link articulated individually so the bracelet hugs the wrist with a suppleness that larger, heavier bracelets rarely achieve. The folding clasp features three steel blades engraved with the Moser logo and a micro-adjustment system, giving the wearer fine control over fit.
Boutique Exclusivity and Final Thoughts
H. Moser & Cie. positions this release as a direct celebration of its growing boutique network, and the Lime Green Enamel edition reaches collectors exclusively through nine locations: Shanghai, Beijing, Hong Kong, Menlo Park, Seoul, New Delhi, Singapore, Chengdu, and the newly opened Chicago boutique. No authorised retailer carries it, which makes the acquisition experience as deliberate and intimate as the watch itself.
The official retail price for this boutique edition is 30 900 CHFÂ excl. VAT. What H. Moser & Cie. offers here is a watch that commits entirely to its idea: no logo, no compromise, and a dial that no photograph fully captures. You need to see it in changing light. That is precisely the point.
