hehehehahahaaaaaaaaaaaa 100 jewels??? There was time (during the 1960's) when we think that more jewels are equaled with better movement of precision. I have never see any simple timepiece or even Grand Complication one with jewels more than a hundred. The other one that with 100 jewels is the Orient Grand Prix 100.
The Waltham Centennial 100 has a unspectacular 17 jewels movement with 83 non- functional jewels embedded in the circumference of the ring attached to the rotor. The jewels count is purely a marketing gimmick and is never a way to make the watch more reliable, or more durable.
The movement in this watch is a third party movement.... The only consolation maybe its rotor is signed with Waltham Geneve. I bought this watch from Philippines as a witness to an era of poor educated consumers.
