Love the squarish shape dials are cool and helpful. ❤️🔥
Color: 2942 All Blue, Color: 2942 All Blue
There's a lot to love about this watch.
The squared profile gives you that big watch look without being gaudy or ridiculous. The blue with gold accents look great with both dress and casual clothes, especially denim.
I love this watch's features and I've gotten multiple compliments on it. great value all around.
Here's what stands out to me:
✅ The blue with gold accents are really stunning and unique. I've had people start conversations with me over this watch. 👍
✅ The squarish shape is complimentary for average and smaller wrists (doesn't look too bulky.)
✅ Gold accents look very distinguished, and the blue is great with jeans or a blue suit, very unique.
✅ The sun and moon dial is a beautiful feature that makes me happy. 🤷😅
✅ The 24hr time dial is extremely helpful. I need to refer to military time so that's nice. 🪖💪
✅ At a glance, the hands and accents are great for far-sighted folks like me.
✅ It's nice to have a date window at the bottom for quick reference.
✅ The linked watch band is comfortable and has a great symmetrical and slim profile that doesn't add bulk and doesn't pull at arm hair.
✅ The band does not sound hollow or jingle. (why I shake it in the video)
✅ The buttons and time setting are easy to access.
I'm really enjoying the quality and look of this watch but if there are any changes in my opinion or its quality, I'll be sure to report back in. 🤞 I hope you found my notes, pictures and video useful. Be well! ❤️🔥

Highly detailed inner face wide and big very manly for a deserving man...
Color: 2942 Silver Black
On par with other Men's luxury Chronograph Dress watches with one exception that levels this up. This has a luminous markers activated when exposed to bright light for 20 seconds. That is something I really like, and not commonly found anymore. My other men's watch is a mechanical swiss watch that you can see the movements and rotaries inside very detailed. This may not have that but this is still very luxurious looking and feeling. This has the luminous markers while my other one doesn't but to be fair, that other one costs above $90, so this was a fair price for this luxurious Men's watch. I find this durable and the clasp gave me no issues.
