This wonderful clock with twenty dials, stands twenty-one feet high, and tells simultaneously the time of all nations; also the day of the week, date and month, and marks the seconds. Four of the dials are each four feet in diameter. The master clock is enclosed in plate glass, so that its every action can be seen, and the whole is illuminated every night. The clock is jeweled with tourmaline, topaz, agate and jade. The jewels and every part of this intricate mechanism was designed and made in our shop. It is the most completely jeweled, best finished and best made street clock in a\America, and the only clock of its kind ever built in a retail jewelry store in the world. The motive power is a 200-lb. weight, and it winds itself automatically. It took fifteen months to build, and cost about $3000. The Master clock was exhibited at the State fair in Sacramento in 1907, and awarded a gold medal.
