Then I met an American, a man called Eckwood, who was frightfully wealthy, I mean wealthy beyond the wildest dreams of avarice, and he wanted me to make him a watch and I had said I would never undertake a commission because the watches I knew would be expensive and I didn't want to be left with the watch, it was too humiliating not to be able to dispose of the watch if you made it for someone. But I took a shine to this chap and I said yes, I would make him a watch and so I set to and designed a new kind of watch, which was inspired by the necessity for beating the quartz watch for timekeeping. The quartz had been introduced in the 1960s, early 1960s, late 1950s, and they kept phenomenal rates of time. I mean two or three seconds a month in those days was very close, and I reckoned I could make a watch to beat that. And so I gave a little thought to what to do to it and the solution was very simple, simply because I didn't want it to be complicated. When a thing becomes complicated, it has less chance of succeeding, the simpler it is the more likely it is to succeed. And so this mechanism was complex, but not complicated, and it proved to be a first class timekeeper and I did a lot of experimenting because I knew very little about watch making. I'd only made one watch and there was a great deal to learn about, especially about timing, because the problem with a watch is that having overcome all the difficulties of design and construction, conception, you've then got to make it keep time. You don't have to do that with any other object in the world. Once you've made it, it's gone. I mean a sewing machine will sew and a motorcar will go, but a watch has got to go straight down the middle, and that's the problem for watchmakers. And so I experimented with ways of overcoming some of the errors that were naturally manifest in watches, and had for the whole of the life of the profession, which was about 500 years. And so that watch was a success and and it was that which prompted Sam Clutton to allow me to buy back the first watch I made for him because he wanted one of these new watches. As ever I knew that once Sam was satisfied with something, the whole world would know and he would be very emphatic you know, and always very willing to push on any new ideas that one might have and he was a great benefactor in that way. He liked progress, he was never happy unless he was improving himself and he loved to help to improve others. So I made him one of these watches and it may have been the lucky thing, but it kept such extraordinary time that on a journey to Tokyo, which took 32 days, when he got home, he'd worn the watch all the time, pocket watch, taken it off at night and laid it down, back in his pocket during the day, and therefore changes of temperature and position and so forth, and he found that it was just under one second slower when he got back. So of course that was a great clue for me. I mean an awful lot of luck involved in that. I mean he never checked it at any other time excepting when he left and when he came back. And so there was no criticism of anything in the intermediate and it did subsequently prove to be a very close timekeeper, because I sent it down personally to Hurst Monceaux, the Royal Observatory for testing. It put up a very good show. It was within 0.2 seconds per day mean variation, which was a very close rate.
