Hamilton X-Mach: Are You Moving Faster Than Sound?
Hamilton’s new 44mm X-Mach lets you measure an aircraft’s speed relative to that of sound – Hamilton calls this the “Machmeter” feature. To perform this feat however, you need to be sitting in the cockpit. Pilots set the pressure altitude (PA) and calibrated air speed (CAS) measured by the aircraft’s instruments by turning the right crown of the watch to reveal the Mach number in ISA (International Standard Atmosphere) conditions on the bezel. Consistent with its mission, the X-Mach is designed to capture the look of aircraft instruments. Both variations (stainless steel with or without black PVD) have a smooth black dial with silver-colored indices and matching counter frames. The case features carbon fiber inserts and white or black numerical markings around the bezel. The case back offers a display window in the approximate shape of a Star Trek insignia, allowing you to catch a glimpse of the ETA 7750 automatic movement inside. The dial has a cut-

Marathon Diver's Quartz Medium review | Worn and Wound
When we last looked at Marathon, I was quite impressed by their affordable and attractive Navigator watch. It was straightforward, simple, legible, lightweight��everything you want in a good day-to-day beater. But the Navigator is really only the tip of the iceberg of what Marathon has to offer. In fact, when a lot of people think of Marathon, they think of their tough-as-nails diver/SAR watches. These big, brutal, mil-spec watches in solid steel aren't kidding around. They are known for their build quality, no-nonsense designs and rugged looks.In somewhat of a surprising move, Marathon released a new entry to their diver line designed for those looking for a smaller option. The descriptively named "Diver's Quartz Medium" takes the looks and build of it's larger brethren, namely the 42mm TSAR, and reduces the package by 20%. The new size comes in at a surprising 36 x 43.5 x 12.5mm. Yup, a 36mm super-tough, mil-spec dive watch. While 36mm is more of a small than a medium (unless they hav

44mm RG or Pt weights?
Can someone with a grams scale please throw their 44mm RG or 44mm Pt on and lmk the grams please?I just read the smaller RGRC actually weighs more than the 44mm due to the sold case back, deployment buckle and RG bezel that's rubber coated.Would also love to know the weight of the 44mm Platty version too!Thanks all!

A Better Eye Needed
So I saw a nice Colt Chrono A7338710 posted locally on Craigslist.It looks like a fake to me, but can someone with a better eye confirm it?

5164A vs 5167A
I want to get a steel aquanaut as my summer watch, we live by the coast so down on the beach and out on the boat every nice day the English weather system gives us.I went to try a 5164A today and loved it. But it's just a little pricey for my expected usage and I don't need the dual time as it will be for day trips only. So I thought a 5167A would be perfect.My concern is that losing the buttons on the left and the thinner case will really make the watch lose its presence as it might wear much smaller.Has anyone compared these two side to side to tell how they wear? Does the 5167A wear much smaller on the wrist?
