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...

What is a chronometer…? In short, it is a watch that has been officially tested for its precision.

Chronograph vs. Chronometer: What is the Difference?

One of the first hurdles to clear for newcomers to watch appreciation is the clarification of two very common horological categories: chronograph vs. chronometer. Quite simply, a chronometer (from the Greek chronos, meaning time, and meter, meaning measure) is any watch or clock that keeps reliably accurate time, usually as determined by an outside independent testing agency, whereas a chronograph (from chronos and graph, i.e., to “write time”) is any watch or clock with the ability to track and record intervals of time, aka a stopwatch. This is, again, the simplest way to look at it. But there’s a bit more to both chronometers and chronographs that a knowledge-hungry watch enthusiast might want to digest - including the fact that the terms are not interchangeable but also not mutually exclusive.  [toc-section heading="Chronometers Defined"]  Our original, classical definition of a chronometer can be traced back to the golden age of seafaring exploration in the 18th Century, when ships required the use of a highly accurate onboard clock that enabled their navigators to determine longitude in order to avoid the perils of running aground or veering hopelessly off course. The man credited with developing the first of these “marine chronometers” was legendary British watchmaker John Harrison; his invention facilitated the celestial navigation used at the time by navigators at sea to determine their ship’s position in coordination with a sextant.
