Watches have always been about more than simply telling the time. A century ago just about every briton lived and worked within earshot of a church, the bells of which would toll the quarter hours regularly as the Greenwich pips do today. But to be able to pull out a polished fob marked you out as a man of importance. Today clocks are built into mobiles and other gadgets we carry, so watch makers have to come up withever weirder ways to make us take notice. The latest? Watches that are deliberately difficult to read.
The most affordable come from Japan, but some of the worlds most exclusive watchmakers also offer impenetrable timepieces.
Hours are displayed on four orbiting satelites. As each comes in contact with the dial at the base it takes an hour to skim across, showing minutes elapsed.
At the 60-minute mark, the next satelite picks up at minute one.
The first dozen LED’s light up one per hour (and the top row of them also shows the name, JLR7). The next three – in a matt band – light up every 15 minutes; the next 14 do so every minute. The final three – also in a matt band every second.
Irregular, rotating polygons cross through ladders of numbers. First look at the edge of the orange polygon. If it slants upwards from left to right as it crosses the top ladder, read the number on the left to find the hour. If slanting downwards, choose from the right. Now look at the white polygon. If the line slants downwards, read off the minutes from left to the bottom ladder; and vice versa if it slants upwards. Its a miracle anyone ever turns up on time in Japan…
A stainless steel band with 29 LED lights. Those below the wavy line light up one per hour, the three to the right represent 15 minute apiece and the 14 to the left are minutes.
This Japanese puzzler is not binary but decimal. The top left light comes on after ten hours, the nine next to it give hours from 1-9 and 11-12; The next five light up at ten minute intervals; the last nine show minutes
