The 2018 Casio G-Shock Rangeman GPR-B1000 adventure watch looks like a glorified steam engine trying to compete with sleek bullet trains.

Already released as the Japanese Domestic Market (ah, that legendary 'JDM' abbreviation that's been rice-rocket freaks' and watch aficionados' darling for so many decades!) models, the 2017 limited-edition Seiko Prospex Diver Scuba Giugiaro Design (available at the time of writing as refs. SBEE001 & SBEE002) is an almost perfect re-issue of the model from the 1980s that had a great potential, but for some reason failed to become an icon of industrial design. I can only welcome the Japanese brand's decision to give the collection a second chance, even as only a limited-edition model.

With its new PRO TREK PRG-600 "outdoor" world-timer, Casio delivers a stylish, surprisingly tastefully designed product. Primarily targeting people who lead an active lifestyle and do need a time-measuring device that would do a good job during a hiking expedition, it will also look great with a pair of blue jeans and a t-shirt in a safe co-working environment. Although inevitably having limitations of its own, the PRG-600-1ER gives you a great combination of good build quality, reasonable price, and an almost overwhelming list of functions that would make an owner of a Swiss-made analog/digital timekeeper drool. The only thing that spoils the fun is the "cased in Thailand" inscription on its machine-brushed back.

The Promaster Navihawk Satellite Wave is an example of how you can turn a block of steel and a score of silicon parts into a wonderful gadget.

The 2016 Seiko PROSPEX World Time Radio Sync Solar Chronograph features exterior design similar to their other aviators from the last 5 years
