| 説明 | I have a particular fondness for analog mechanical watches featuring unique mechanisms or design. I am fairly certain no one else has this eclectic assemblage, even if I ignore the watch that the NASA Administrator took with him for his first orbital spaceflight. Deets:1) Alt-Smart Watch, with a cephalopod intertwined front and back. The eye holds the mainspring.2) The newest Patek design, and my first. I especially like the use of dual number discs on the same plane for a large date display up top. It’s thin, but wearing it, I can tell platinum is almost 3x denser than steel.3) The Freak-S, Serial Number 69 of course. This is a bit of an engineering marvel as the entire watch caliber is built into the minute hand which drives a tiny gear rolling around the outer rim, and it drives the hour hand below. It took MEMS silicon manufacturing to make tiny escapement gears so a double tourbillon with differential fits in the hand. And it has no stem.4) A unique perpetual calendar that does not have any buttons, just a single stem. It keeps a record of date and moon phase for centuries, accounting for the odd months and leap years in the mechanical clockwork.5) An odd tumbler. The turntable flips the hour wheel to show the time on the right side. Looking at it carefully, I realize that it achieves all of the motion from a single central shaft rotating 3x slower than a usual hour hand. A stationary peg in the face catches the smaller wheels to rotate them a quarter turn as they pass by. The face is labradorite, one of my favorite minerals.6) My current fave, as it is so unique and visually striking, and a bit mysterious. It’s also the first of its kind in North America. The hours are tiny cubes that rotate so that only one has a white face up. The tourbillon is centrally mounted, and all of the clockwork and self-winding mechanism appear to float in the center of the case. And that’s the mysterious part: none of the tumblers touch the rim, and given the moving pieces front and back, it is not attached to either sapphire face either. Want to guess how they did it?7) Flown bespoke SpaceX Inspirati④n watch from Mission Commander Jared Isaacman. He sold it to me in a St. Jude Children’s Hospital charity auction. Jared wore it in space on the three-day mission, the first flight of an all-civilian crew, as covered in the Netflix documentary Countdown. The body is a unique white ceramic that’s harder than any other watch body.8) A fanciful frolic called BR-03 Astro, with a Starlink satellite in Low Earth Orbit (seconds), Luna on the horizon (minutes), and an hourly Mars floating in the distance, beckoning us.And there you have it, some of my favorite things... anachronistic chronometers as they may be. If you made it this far, which would be your fave? |
