in case you are in the market for cx20k, here are some comparison shots with rolex divers and some other well known watches.
The CX20k is avery difficult to get watch to try on. I bet everyone who buys one, never gets a chance to try one on, except after buying it. You can not go to a mall and try it on --- Extremely few people carry it and 99.99% of the time, they are out of stock.
So here are a bunch of pics for size comparisons-- the last 2-3 pages are with the DEEPSEA.
