Really happy with this watch. The quality is better than I expected, especially for the price and the band steel feels solid and the finish looks great in person.

Brian Mitchell

Been wearing this all summer and honestly the quality surprised me. It feels really solid for a full steel watch and has a nice weight to it. The water resistance is a big plus too, especially during summer. Very happy with how it turned out.

David

Honestly, I’m really happy with it. The watch looks great on the wrist and the quality is better than I expected. Got a lot of compliments already. G-TUNE were great to deal with too, everything was straightforward. Would definitely buy from them again.

Wear this thing everywhere, gym, work, even when I'm out on the bike. Still looks brand new after a few months. Didn't think a mod like this would hold up this well honestly. Really happy with my purchase and watch design. Good support team also!

J
Jamie H.

I came across these luxury G-Shocks online and decided to give one a try. I really liked the option to create my own custom design, so I ordered a full steel watch with the premium GM dial. It turned out to be the best choice I could have made. The watch looks absolutely incredible, especially for the price. It honestly looks like a $1,000+ G-Shock. Highly recommend!

Gabin S.

Came with everything included and a sizing kit so I could adjust it at home. Honestly didn't expect it to look this good in person. For the price, nothing comes close. Highly recommend.

M
Martin

The watch is a great buy for the price, looks very good in person. The only problem was that the watch took a bit of time to arrive, but outside of that everything is on point.

Got my custom G-Shock today and arrived in perfect condition. Looks even better on the wrist than in the photos, quality exceeded my expectations. Took a bit to arrive but for a custom watch, totally worth it. Love it!

Looks way more expensive than it is

Been wearing this thing every day for weeks now. The steel bracelet and bezel combo is just clean, gets compliments constantly and nobody believes it's a G-Shock underneath. Solid purchase, zero regrets.

Premium Look, Better Than Expected!

I ordered a custom watch with a steel bracelet and the premium blue dial a few weeks ago, and I’m genuinely impressed. The watch looks far more expensive than it actually is and looks amazing for everyday wear. The package arrived well protected and included everything the store promised. Overall, I really loved the experience and would definitely recommend it.

Looks like a luxury watch.

Really happy with this watch. Been wearing it for a week and it looks great. Feels premium, way better than expected for the price. The store was solid too, fast support, no issues. Would definitely buy again.

Custom Watch Exactly How I Wanted

I decided to go with a full silver steel strap and case with the GA-2100-4A red dial, and I absolutely loved the final result. The steel feels high quality and the watch fits perfectly on my wrist.
I really enjoyed the opportunity to design my own watch and receive it exactly the way I imagined. This store has a really cool concept and a great team that answered all my questions.

Had to buy

A few months ago, I saw some videos from G-TUNE featuring these G-Shock mods. I noticed the difference between a regular G-Shock and the G-TUNE mods, and I had to buy one. For a full steel watch, the price is amazing, and for the quality you get, this watch could easily be over $500, but it isn’t. I paid $350, and it’s one of the best watch purchases I’ve ever made. The watch looks perfect on my wrist with a luxury look. I’m really happy with my purchase!

Max
100% worth the money and the wait!

I ordered my first G-Shock mod from G-TUNE 3 months ago and loved it so much that I had to go back for a second one. This time, I designed a custom premium version myself, and it’s already the favorite in my collection. The quality is insane for the price point, and getting 10% off the second order makes it an unbeatable deal.

Great product overall

The watch is great for the price, got it on sale and I like it. The watch case has a good quality steel and the band is confortable. Only problem was shipping, it take some time but they solved it and respond to all my emails.

This G-Shock is clean with a premium look.

Had to use a glove to take the picture, ahah. This G-Shock is clean with a premium look. The stainless steel case gives it that premium vibe, but it still feels like a proper everyday watch. Nothing too flashy, just solid and well built.

The black dial and strap keep it low key and comfortable on the wrist. Overall, it’s a sick upgrade from my classic G-Shocks. Store service is also good

The best watch shop I've come across

I discovered this brand through an ad. It caught my attention because my husband has always loved watches, especially G-shock. I notices that their watches looked very different from the usual ones, with a much more luxurious style. I immediately knew I had to order one that my husband would like for his birthday. He absolutely loved the watch and now wears it almost everyday. The customer service was very friendly and helpful throughout the process. I really enjoyed the whole experience
