Why Leap Day Matters

Jason Pitsch

As you likely already know, today is leap day, meaning this is a leap year. Typically years divisible by 4, such as 2016, 2020, and 2024, will have a leap day. If the year is divisible by 100, but not 400, there is no leap day. A complete revolution of the Earth around the Sun takes longer than 365 days, and so a leap day takes this extra time into account so as to realign solar time and the Gregorian calendar (which is the calendar we use). One solar year takes 365 days and 6 hours, therefore, every four years, there are an extra 24 hours, which explains an extra day. Crucially, the Earth actually completes its orbit around the Sun a little bit less than 365.25 days per year. The number is actually more like 365.2425 days per year,

Arnold & Son HM Double Hemisphere Perpetual Moon

Jason Pitsch

The Arnold & Son HM Perpetual Moon, which has one large cut-out depicting the moon phases as seen from the Northern Hemisphere, is now available in a dual hemisphere model. Interestingly, because the secondary moon phase dial – located underneath the main dial – already has two moon discs on the single hemisphere model (the 11.2 mm moon discs are mirror images of each other), the new HM Double Hemisphere Perpetual Moon is able to utilize the same exact movement (caliber A&S1512). In fact, the only difference between the dual and single hemisphere models is the additional cut-out on the lower half of the dial, and a new marking in the center that shows indiciates the northern and southern hemispheres.

Baselworld 2016: Grönefeld 1941 Remontoire

At Basleworld, next month, independent Dutch watchmaking brothers, Bart and Tim Grönefeld, will unveil a new timepiece, highlighted by an eight-second constant force mechanism that ensures that the power delivery never fluctuates from the point that the mainspring is fully wound (36-hours) until it is completely unwound. This leads to consistent rate and amplitude, and excellent precision. The inspiration for the creation of the Grönefeld 1941 Remontoire came from the brother’s childhood, where they played to the sounds of the Saint Plechelmus church clock, which was maintained by their grandfather, Johan Grönefeld, until he passed away, at which point their father, Sjef Grönefeld, took over the duties. According to the manufacture, “The church clock, created in 1913 by Royal Eijsbouts in the village of Asten, The Netherlands is equipped with a remontoire mechanism. The rationale for the remontoire being used

Introducing the Angelus U20 Ultra-Skeleton Tourbillon

Baselworld 2016 is just around the corner, and Angelus has provided a full preview of their soon to be released U20 Ultra-Skeleton Tourbillon. Made of carbon and titanium, the (42 mm x 10.30 mm case) houses a movement that was designed to be a skeleton from the start, instead of taking an existing movement and removing material – as is typically the case. And thanks to an ingenious structural design, supported by a sapphire crystal mainplate, caliber A-250 truly appears to be floating in the case. Crafted of blued titanium, the bridges have a distinctive beam shape that was designed to increase rigidity. And like virtually every other component, even the bridges are skeletonized – further enhancing transparency. The balance wheel, which oscillates at 3Hz, is supported on the front by a rotating one-minute flying tourbillon, which helps offset the

Jason Pitsch

In addition to the new Laureato we showed you earlier this month, Girard-Perregaux will debut a new openworked timepiece at Baselworld 2016, called the 1966 Skeleton. Based on caliber GP1800, the anthracite gray ruthenium movement has been skeletonized, and then hand chamfered, polished, and satin-brushed. Automatic caliber GP01800-0006, consists of 173 total components, 25 jewels, and has a 54-hour power reserve. Visible at 12 o’clock is a Microvar variable inertia balance that oscillates at 4Hz (or 28,800 vibrations per hour) and is exclusive to Girard-Perregaux. A sleek 38 mm x 9.27 mm 18k pink gold case, with a sapphire caseback, houses this impressive movement, which displays just hours, minutes, and seconds. Leaf-shaped hour and minute hands correspond with the chapter ring, which consists of applied hour indexes and minute transfers, on the flange – because there is no actual dial.

Richard Lange Jumping Seconds

Jason Pitsch

One of the most interesting Lange debuts this year was the Richard Lange Jumping Seconds. Introduced at SIHH 2016, the watch is distinguished by its regulator dial that separates the hours, minutes, seconds on separate axises. Most importantly, the seconds hand, in particular, “jumps” in one-second intervals. At first glance, you might think it is quartz movement that powers the hands, particularly because the seconds hand on a quartz watch also jump in one-second intervals, instead of smoothly sweeping like the majority of mechanical timepieces. But this is far from quartz. Driven by a one-second constant-force escapement, the so-called “deadbeat” seconds feature, when combined with the zero-reset mechanism, makes it so you can out the crown, instantly causing the seconds hand to jump to 12 o’clock and stop, allowing you to quickly and precisely synchronize the timepiece. And thanks to
