A Thin Watch with Signature G-SHOCK Toughness
At only 11.8mm thick, the watch case creates a slim profile that makes the 2100 series a comfortable everyday watch. Although wonderfully thin, the GA2100-1A doesn't skimp on protection. G-SHOCK innovative design utilizes a Carbon-Core Guard Structure that begins with an advanced carbon fiber-reinforced resin case. The entire GA2100 series maximizes the utility of a compact design while advancing the G-SHOCK legacy for crafting some of the toughest watches on the planet. 200-meter water resistance (wr 20 bar) and scratch-resistant mineral glass round out an incredible array of protection. Weighing only 51 grams, the GA2100-1A packs all this protection into a comfortable watch whose sleek, thin profile is magnified by its dark styling.

Technological innovation abounds in the compact case of the GA2100. World Time displays the time in 31 time zones (48 cities), great for coordinating global business or keeping in touch with distant family and friends. A stopwatch, timer, and five daily alarms help you to organize your day, keep track of important ongoing tasks such as cooking and project time tracking, and stay focused without the need to shift your attention to a screen. The stopwatch offers elapsed time, split time, and 1st and 2nd place times. Keep an eye on your children's screen time with elapsed time or utilize the split time to measure various segments of an important presentation and track segment pacing in a natural flow.

Good sunscreen great price
Seems to work well. Feels good on my face. Does leave a white cast but it's not as bad as other sun screens like the Neutrogena sport face. I wear it at work so I don't care. Edit- this sunscreen seems to break down some plastics. I've gone through two cheap sunglasses lol

Love this for my face!
Neutrogena SPF 100 sunblock lotion is the only sunscreen I trust and use on my face. It gives amazing protection without making my skin feel greasy or heavy. I’ve tried so many different sunscreens, and this one works the best for me. It absorbs nicely, doesn’t leave a bad white cast, and wears well under makeup too. A little goes a long way, and I love knowing my skin is protected, especially during summer or long days outside. Definitely a staple in my skincare routine!

Good sunscreen but be careful around your eyes
I’m trying to get better at using sunscreen more consistently, so I’ve been on the hunt for a while for the perfect formula (ideally SPF 100, not greasy, and would work well under makeup for when I’m both outdoors and wearing a full beat). I liked that this seemed to tick off all my boxes while also being affordable because if I’m going to use it frequently, I want to rest easy knowing that it won’t break the bank. I also vaguely remember using this sunscreen (or at least this brand) many years ago with no issues, so figured it’d be worth going back to. I normally use three thick finger lines of sunscreen for my face, neck, and ears, regardless of spf number, because if I’m going to go outside I’m not taking any risks. (Usually the rule of thumb is two fingers.) Also depending on what I’m doing and how long I plan on being outside, I try to also take the bottle with me so I can reapply. Anyway, I test it out, wear it, feels good. Takes a little while for it to feel relatively dry as advertised, but once it dries it’s tolerable. By the end of the day you might forget you still have it on your skin (aside from maybe the slight sunscreen smell, nothing terrible). Washed it off in the shower as usual. Most of my face still looks perfectly fine, but my undereyes are now red! (Or at least one of them, for some reason my right undereye is more sensitive than the left.) From what I’ve read online so far, it might be a sensitivity to avobenzone, one of the active ingredients. Very baffled with what to do because everyone says to use sunscreen around your eyes because of aging and sunburn, but does that mean I have to get used to my eyes turning red just to get that protection? I already wear pretty big sunglasses too, so it’s not like they’re completely exposed. Will have to experiment some more and/or look at alternatives.

Good, inexpensive sunscreen
I have always loved Neutrogena products especially their sunscreen. It used to be hard to get SPF over 30 and now they have it up to 100. I haven't burned using Neutrogena, haven't had any skin issues and it's pretty inexpensive. Would recommend.
