    Solid Watch 2 Months In TLDR, would buy again
    Color: Black/Black/Digital
    Solid watch so far with a readable face and a comfortable strap. My previous watch was a G-shock DW5600. I chose this for the lap feature and generally liked the appearance. Things I didn’t love: 1) the chronograph displays the mode at the top. I know what mode it’s in, it would be better to have the actual time. 2) this has dual time zones, it’s apparently easy to flip to the second time zone without realizing. I have mine set to US eastern and US central (a one hour difference which begs the question why, and I hear you). But I almost missed 2 events not realizing my wristwatch had jumped back an hour while playing with my kids in the park. 3) I’m still playing with the count down timer function. I messed something up on my first run, but I’m sure I’ll figure it out. Just something didn’t work intuitively. 4) I didn’t realize how often I had used the indigo equivalent feature on my Gshock as a flash light in low light situations. With the black face this isn’t an option on this watch (I’d still make this trade for the aesthetic). I would buy again just for something fresh after 5+ years with the G-Shock and the lap feature. Probably a little hyper critical focused on the short comings. Water resistance has been tested an no issues after two months.

    Tough as hel
    Color: Black/Black/Digital
    This watch hasn’t left my wrist in 5 months and has been through hell and back. Has all the features I’ll ever need. Bought a second one to keep in case they discontinue it in the future.
