The estimates on these two watches are pretty serious 100 watch is estimated at approximately $205,000-310,000, while the 37mm watch is estimated at approximately $258,000-413,000 100 in platinum would be the more expensive of the two, but the 37mm is generally considered more wearable, and the larger size makes it more popular with most modern buyers.
