While a lot of the atomic clocks on the market share the most basic features, it's often the extras that set them apart, and knowing which of those would serve you best can go a long way toward giving you a sense of which model is right for you. If you want to pack as light as possible, for example, the wrist-worn Casio G-Shock 4ACR is a fine option, even if a watch isn't what you immediately think of in a category of clocks. But if you're traveling by train without the luxury of a sleeper compartment, and you need to wake up in time to get breakfast in the dining car, you'd do better with a quiet watch alarm than a loud digital clock.
Then, there are certain area-specific features, like 24-hour time and climate information. The Marathon CL030054BL Desk has perhaps the most interesting of these features, integrating temperature and humidity information into a simple index that can guide how you should dress and what to expect as you head out to explore an unknown city. The signal on this model isn't terribly consistent, however, so it may speed up or slow down by fractions of a second per day, which certainly isn't a deal breaker for many, but some people looking for a radio-connected time solution want that constant recalibration to keep them as accurate as possible.
