    • Indestructible el compañero ideal para el taller
Review Image by Jhonathan Moriones
Compré este modelo por su resistencia a impactos y al agua ha superado mis expectativas el interruptor giratorio, es muy intuitivo y fácil de usar. Incluso con las manos ocupadas es robusto y aguanta perfecto, el ritmo del taller 100% recomendado.

    • Great watches
Real nice watches,but if you get the ones with 2 batteries let a pro change the batteries, I found out the hard way by trying to do it myself and broke a couple of little tabs which is why I had to buy a new watch. Its all good though!

    • Very G-Shockey
What you'd expect from a G-Shock watch at this price point. Chunky, rugged, and "tactical" looking with good build quality. The only thing, and I wouldn't consider it a real complaint, is that the light doesn't do a good job of illuminating either the digital displays or the analog hands in the dark. ... show more

    • Non functional watch, poor support, Don’t buy
The new watch is non responsive even after spending 4 hours. Normally all new clock is calibrated to 10:10 AM, this watch came with 11:20AM on it that is a indication that it’s a product returned by a previous customer. Connected to chat room to troubleshoot after spending 4 hours to make it work. In a matter of 2 minutes all 9 associate joined left. All of them were non responsive. The watch was a gift to my cousin and it completely ruined his excitement. Ended the chart and escalating to the Amazon service and hoping to get full refund. Also they will deduct $20 from the total refund as the item was returned after the refund duration is over, even though it’s a defective piece and doesn’t meet the customer expectations. So please start shopping from other places. ... show more
