Most practical watch
I'm a watch collector and I enjoy classic men's watches. One thing that I can't stand is that no matter where you turn around you always see bunch of people with the same exact smart watch of a certain brand on their wrists. So boring. So cliche. So annoying. As the phones aren't enough. Anyway, excluding this Casio that I bought last year out of nostalgia, I have 6 other watches with combined value of $30K: a Sea Dweller, a Seamaster, an Aquaracer, a Seiko Cpt Willard, a Seiko Arnie and a Citizen Nighthawk. Yet I wear this cheap $100 Casio most of the time - when I'm outdoors, when I'm at home, in a pool ..... - Virtually 90% of the the time and situations that don't warrant wearing a luxury/dressy watch. That says enough how much I like this retro looking G-Shock! It's by far the most practical watch I have and it has all the features you would want in an EDC watch: toughness, solar power, waterproof, alarm, timer, date, light, multiple times zones...
I highly recommend it for men of all ages, backgrounds and lines of work.

The perfect "set it and forget it" watch
I finally decided to swap my smartwatch for something simpler, and honestly, I couldn't be happier with this G-Shock.
The best part is definitely the zero maintenance aspect. Since it's solar powered, I don't have to worry about charging it or swapping batteries. It also has Multiband 6, which basically means it syncs with atomic clocks every night (assuming you're in range of the broadcast tower and have good signal). It is literally never off by even a second. If you’re someone who values total accuracy but wants to go a bit more analog, this is definitely the one.
It’s as rugged as you’d expect. I’ve already taken it to a water park and beat it around quite a bit, but it still looks brand new. It’s nice having something on my wrist that I don't have to baby or worry about scratching.
The only real downside is that the buttons are pretty recessed, so they can be a bit of a pain to press. You kind of have to use your fingernail to get them to click. It’s a small trade-off for the durability, but worth mentioning if you have bigger hands.
Overall, if you want a bulletproof watch that’s always accurate and never needs a charge, you can’t really beat this classic.

Great Watch!
Excellent watch. Extremely low profile considering all of its features: Six-band atomic clock reception around the world, 200 meter water resistance, stopwatch, timer, alarm, shock resistance and you hardly notice you’re wearing it! If you buy this watch scan the QR code in the English portion of the instruction manual. It provides a much more clear explanation of how to use the watch’s features. Not bulky but loaded with stand-alone features. It’s not dependent upon a cell phone for anything it provides and it charges with any light source. It’s awesome!

My New Favorite Everyday Face Sunscreen
Color: 04 - Untinted (1.7 oz)
I’ve tried quite a few daily sunscreens, and this one stands out for how refined it feels on the skin. The texture is elegant, moisturizing, and absorbs beautifully without the heavy, greasy finish that so many SPF products leave behind. It gives my skin a smooth, comfortable feel while still delivering dependable daily protection with zinc oxide and SPF 40.
What I appreciate most is how seamlessly it fits into a morning routine. It layers well, feels gentle, and leaves my skin looking polished rather than coated. For dry skin, it strikes a really nice balance between hydration and sun protection, which makes it feel more like a true skincare step than just sunscreen.
Overall, this is a very elevated everyday SPF — simple, effective, and well formulated. If you want a face sunscreen that feels sophisticated and consistently pleasant to wear, this is an excellent choice.
