No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

Solid all-around watch
Color: Grey
I was looking for something that I could wear just about anywhere. I wouldn't wear this to the gym, but it looks good in casual, work, elevated, and even some dress environment. Black-tie, I might look for something a bit more elegant, but 95% of the time, this watch fits. Keeps good time. I haven't witnessed a full 80 hour power reserve yet, but I also can't say that I ever needed that much. Lume is nice, just give it a chance to charge up. I like this more than the PRX. It's a more classic look, I think PRX will look silly in a short time in comparison.

Excellent value, beautiful aesthetics
Color: Grey, Color: Grey
This watch confirms what is mentioned in reviews all over the internet- a great value proposition in so many ways. Accuracy has been +3s/week, well within specification, and rivals that of much more expensive watches, including chronometers. The bracelet has a quality feel and heft, and the case contours nicely to the wrist and is very comfortable. The green dial appears to change color with different angles and absolutely pops in the sunlight. Highly recommended, even as a first automatic/mechanical watch.

Very well built, will last you a very long time
Style: Trifold, Style: Trifold
This wallet is very sturdy, and barely has any wear on it after I've purchased it over a year ago. Most wallets will start to greatly scuff, wear, or degrade/break down just from being taken in and out of your pocket but this wallet has held up particularly wear with VERY MINIMAL light scuffing. Quality leather so I know I will have this wallet for a very long time! It has great card holding capacity as i currently have about 10 cards in it and it still has a pretty slim profile. The wallet itself is a very nice, natural looking wallet. The ease of pulling cards in and out definitely has made me a fan.
