The H. Moser & Cie. Streamliner Small Seconds Blue Enamel, reference 6500-1200, is a steel sports watch with an integrated bracelet and a grand feu enamel dial. The cushion-shaped case measures 39 mm in diameter and 10.9 mm in height including the sapphire crystal, and it is water resistant to 12 bar (120 m). The dial is Moser’s translucent Aqua Blue fumé grand feu enamel, applied over a textured base in several layers and fired about a dozen times so that the colour darkens towards the edge. It carries applied steel hour markers without lume, a small seconds sub-dial at six o’clock and no logo, while the hour and minute hands have luminous inserts. Inside is the automatic calibre HMC 500, a partially open-worked movement with a solid platinum micro-rotor that winds through a bidirectional pawl system. It runs at 3 Hz (21,600 vph) and has a power reserve of 74 hours.

Moser launched the watch at Dubai Watch Week in November 2023, together with the new HMC 500, which Watchonista describes as the smallest movement the brand has developed in the 21st century. It was the first Streamliner with a fired enamel dial and introduced a slimmer 39 mm case to the collection. The dial keeps the size of the centre-seconds Streamliner, which gives it a large, retro look in the smaller case. Through the caseback, gilt wheels contrast with dark grey plated bridges. The watch is delivered on the integrated steel Streamliner bracelet. It is not a limited edition. The launch price was CHF 29,900 excluding taxes, about 50 percent more than the centre-seconds model, and Watches of Switzerland lists it at USD 39,000.

Watches By SJX found the enamel dial attractive and an interesting alternative to the blue dials common in luxury sports watches, and praised the movement’s design with aesthetics in mind. It also called enamel a peculiar and somewhat mismatched choice for a sports watch, given its fragility compared with a brass dial, and judged the value less appealing than that of the earlier Streamliner. On the secondary market, pre-owned examples have been listed at roughly EUR 31,900 to USD 42,000, broadly in line with retail. As of October 2026 the Streamliner Small Seconds Blue Enamel remains listed on Moser’s website and is in production.
