Collectibility
Because they are no longer in production most of the Masters series command strong resale values; examples in NOS (New Old Stock) condition command a premium. Prices are sometimes higher outside of Japan, not least because many models were produced only for the domestic market rather than for North America and Europe.
There have been several limited editions of the Masters series, and depending on their scarcity these command some of the highest prices for any of Casio watches. The Men in Black and Men in Yellow series are black and yellow versions of the Masters and typically command anywhere between two and three times the resale value of the regular versions. Some models such as the "Brazilian" Frogman and A.R.T.P.I Wademan are even scarcer and can command even higher prices, though their value is hard to predict as there are limited numbers and the price is largely determined by demand from individual collectors.
Although not always available, all models are usually valued at 500 USD or less, providing an affordable alternative to the collecting of prestige watches.
