[ProTrek Review] PRG-600YB-3ER with a wider nylon strap

The Ultimate Guide to All PROTREKs — composed by Experts

Casio ProTrek’s PRG-600 series of travel destinations continues to be a personal favorite among the many outdoor creations of the Japanese brand. Of course, I do not yet take into account the very fresh G-Shock Rangeman GPR-B1000, which will give odds to any tracks in principle. Forget about them and consider the so-called tourism classics, PRG-600YB-3ER watches.

Damn, did I really forget … No, g-shock fans and KO, I wanted to feel the PRG-600YB-3ER with a fabric strap. I don’t know why, but fabric straps have long been my weakness. The thread, as for me, fits perfectly with the ProTrek philosophy.

What can I say, the PRG-600YB-3ER look chic. The strap is made in a modest minimalist style. The fabric is very dense, it bends hard [agree, a solid indicator].

This is definitely not a rag with which you can wipe the table. The place near the mount with the body is repeatedly stitched with a thin thread.

Strength is beyond doubt. Stitched for centuries. Another important point – the strap is quite wide. If silicone is trying to be narrow, then tissue is the opposite – it widely covers your wrist.

The metal clasp deserves special attention. It is matte, also in a minimal style, and for some reason I really like its look. The watch has two leather strap holders.

The decision is logical – the fabric version would be very thick and bulged.

Further, the PRG-600YB-3ER case itself … Again, I will not dwell on all the features [functions and technologies] for a long time, because you can read the first review, where I have thoroughly gone into all the details.

Now, I want to show you the PRG-600YB from different angles to recall the existence of such a beautiful model.

The color tone of the watch contributes to the perfect readability of information. The hour markers, buttons, and hands contrast so strongly with the black background. It is impossible not to notice the exact time.

A thin light strip on the crown [SMART ACCESS] is another design element for a harmonious combination with display elements.

The backlight button is so easy to find. Ideally disappeared almost at the place of attachment of the strap [under the 6-hour mark].

Compass, barometer, thermometer and other advanced electronic functions work only in digital mode. Although not, in compass mode, the second hand acts as a direction indicator.

This is how the backlight works. In the last review, I was able to better convey the excellent readability of information in the dark:


PRG-600YB-3ER can be called “SUVs” in the world of ProTrek-s. It seems like there are a lot of functions, use at least in the desert, but such a case focuses on ordinary active citizens. Arrows are not always convenient from an extreme point of view, but ideal for a life mix.
