The Seiko Prospex Speedtimer have just added three new references to its lineup, two being the models powered by the 6R55, and one chronograph piece powered by the 8R48 movement.

Starting things off with the non-chronograph models (SPB513 and SPB515), you get a dial that is either silver-white or black, with tiny pops of orange on the countdown timer and the seconds hand to add just the right amount of variety to the look.

These are simple three-handed movements, with a date window, and despite its small footprint on the entire scale of the watch, the date window is one of the most elegantly executed ones in the world of horology. Because date windows at the four o’clock position are already a challenge to present, and here, just like the other Speedtimer predecessors, the complication looks almost chic, despite the sporty package it is encased in.

The second crown that turns the inner bezel is a breeze to operate, but this exact smoothness may be the exact reason why it should not be used in rougher environments — it would not take much to turn the crown and change the indicator. Still, it works well fordaily use, such as timing your boiled eggs to perfection.

The 6R55 movement features a 72-hour power reserve, beating at 21,600 vibrations per hour. It is reliable, and will make for a good watch to wear both regularly or on occasion. Of course, with a case of 39.5mm in diameter and 12mm in thickness, it will be easy to rock this watch as a daily driver. The 200m water resistance definitely helps.

The other new model in this series is the SRQ055, which offers the chronograph complication. It runs with a 45-hour power reserve at a frequency of 28,800 vibrations per hour. Its dimensions of 42mm diameter by 14.6mm thickness make it the perfect size for legibility, especially with the sub-dials included in a watch of this build.

Compared to its smaller siblings, this watch only has a 100m water resistance rating. Plenty for urban life, though it is rare to want to wear a chronograph in the water, anyway.

This watch has its fair share of smooth operations, too. Thanks to the vertical clutch design, the chronograph operates in precise clicks every time the pushers are activated. This is because the vertical clutch system does away with the snagging of the gears, eliminating the stagger that comes with a horizontal clutch system. And make no mistake, there are watch fans that actually appreciate this tiny detail, especially when it comes to the chronograph.

All three of these watches come in a stainless steel bracelet, and the five-link design sets it apart from the traditional three-link variety. Each link is short, meaning that the bracelet articulates better and feels more supple on the wrist. The clasp offers the micro-adjustment features as well.

These new models are all in constant production, and they are very reasonably priced as well. That only goes to say that it would be a waste not to own one of these solid timepieces, and whichever one you pick, it is bound to be good.
