HANDS-ON: Ulysse Nardin’s surprise sailing watch - the Marine Regatta

Ulysse Nardin made their name way back in 1846 making marine chronometres – highly accurate ship’s clocks that were an essential navigational tool in the times before radio and GPS. These days the Le Locle-based brand still makes chronometre-style timepeices, but as a celebration of heritage rather than a practical tool. This isn’t to say that … ContinuedThe post HANDS-ON: Ulysse Nardin’s surprise sailing watch – the Marine Regatta appeared first on Time+Tide Watches.

Introducing: Serica Downsizes Its Field Chronometer With The 35mm Ref. 7505

What We Know It's time to put aside the debate of big watches versus small watches. I think we can at least agree that options are a good thing, so everyone can get what they want. With that in mind, Serica has released three new, smaller Field Chronometer watches measuring only 35mm by 9.6mm thick with a COSC-certified automatic movement and three new enamel dials. These three new watches, with stainless steel cases, play off the design language of the ref. 6190 with a few tweaks. There's the slightly larger, fixed bezel with pips at 3, 6, 9, and 12 o'clock. They have a double-domed anti-reflective sapphire that should somewhat magnify the smaller dial. The two-tone cream-and-black "Tuxedo" dial is similar to the ref. 6190 TXD, with hand-applied numerals. The other two, the "Minute Critical" dials in black or olive green, aren't that far from the ref. 6190 "Denali" that is already on offer in a larger size, with added 5-minute Arabic numerals. All three have Super-LumiNova C3 lume. Inside the case is the SoProd M100 movement, which is COSC-certified for accuracy, making it a Field Chronometer in both name and function. The caliber runs at 4Hz, is self-winding, and has a 42-hour power reserve. According to Serica, it also has a decorated plate with Côtes de Genève, and while there are no photos of the caseback, I would assume it is still a closed caseback like its big sibling.  Then there's the final major update: the watch comes with a redesigned Bonklip bracelet, fea...

Serica Introduces the 5330 Dive Chronometer

One of watchmaking’s simplest but most iconic complications, the date window, is the source of much admiration, and yes, a little bit of ire. One of the biggest points of contention on any inclusion of a date window is the balancing of it on the dial; after all, how do you place it to not ruin the symmetry (or asymmetry) of a carefully-crafted design? With their new Ref. 5330 Dive Chronometer, Serica has chosen a sleek solution for their first date window inclusion: nestle it at 3 o’clock, taking the place of the marker, and give it a crisp red accent to stand out. Sure, it’s not necessarily revolutionary, but it adds a sophisticated touch to an already clean dial. The core tenets of the 5330’s design carry over from other models in Serica’s Dive Chronometer lineup, with circular hour markers and a double graduation bezel being the most recognizable, and a 39mm 316L stainless steel case housing an identical SoProd M100 Swiss automatic movement. The matte black dial and anthracite-grey outer bezel ring contrast with the steel of the inner bezel and case, and the cream Super-LumiNova on the hands and hour markers. Similarly, the cream date window and red numeral add both a sense of cohesion and a highly legible flash of color to give the dial an extra layer of aesthetic complication. It’s certainly a welcome addition visually, and keeps the design from feeling too austere.  At 12.2mm in thickness and 46.5mm lug-to-lug, the 5330 is sized well for most wrists, and...
