Beautiful timepiece, and the quality feels phenomenal! It got some weight to it which is super nice. Overall from customer service to delivery 10/10.
This watch is a showstopper. Absolutely love it. First time I’ve ever had people stop me and ask me about a watch. Shines like the real thing, but with extra features like a transparent case back. Movement feels solid and keeps super accurate time. I love it!
Watch finishing and movement is really great quality which is beyond my expectations. It’s worth to by from Modsera
Var lite skeptiskt från början men fick hem en väldigt fin klocka!
Kommer beställa en Datejust också👍
I’m really happy! I’ve been in frequent contact with Customer Service, who responded to me faster than I’ve ever experienced with any customer service it wasn’t even 30 minutes before I got an answer to my question! This company truly does everything they can to ensure their customers are 100% satisfied, highly recommended! When you receive your watch and see these masterpieces up close, you won’t regret it, just make sure you know which diameter suits you :)
Was looking to elevate my watch style as I’ve worn the same single watch for the past 3 years. I love the quality as well as the craftsmanship. These almost make buying a Rolex not worth it !
The products are of high quality! And the customer service is outstanding! They answer fast, helps with whatever is needed! I rate them 10/10! I have bougth alot of watches from them, and will continue to do so!
I highly suggest buying these. Feel tremendous on the wrist and the seiko movement is always on point
Took advantage of Modsera’s 3 for 2 deal and absolutely love all of the watches I got. They all hold great time, are super easy to adjust the links, and the customer service and response time to any questions was superb. Definitely will be a return customer!
I’m still in shock of the quality of my watch! I was so skeptical with custom making mine, but after I got it in the mail, it was totally worth it. I’m already looking at buying two more…
I am very happy with my GMTeiko rosegold rootbeer.
It is beautiful and run great on time. Great watch
Amazing product, great customer service and the shipping was fast. Definitely going to order more
Did the 3 for 2 deal and wow are these watches well made. I have almost 20 watches and most are seikos and I can honestly say the bruce wayne gmt I got as one of my 3 is easily my favorite watch of all the ones I have already. Great builds.
I think the watch looks amazing and it feels amazing! They took their time putting it together and you can see it. I wish that it came with the metal back rather than the glass one, like in the advertised picture. Shipping says 4-8 days, but mine actually took 22 days to be delivered from the day I ordered it. Which kinda sucked because I wanted to take it on my vacation. Overall I give it a 4.5 stars.
Awesome watch very happy and satisfied with timepiece and addition to the collection. I got email updates throughout the build and shipping process. Customer service like this is not normal. Good experience!
This watch is such a striking statement piece! I love it…it’s exactly what I’d been hunting for. I’m a woman who wanted a larger face with bold but classic appearance. The cyclops lens showing the date is perfect! The only thing to improve is the closure clasp…it is a bit stiff to open. There’s a smaller over-clasp that is easy, but the big clasp piece is a bit tough to open. I think that will get better in time. Overall, I’m very happy with it! I added a beautiful diamond peace sign dangle charm and I’m thrilled with it all! Thank you!
I love this watch! I have been getting complements on it non-stop and I feel great wearing it. It is just an awesome piece. It is also really comfortable, which I am super happy about. I have another watch like this that I purchased from a cheaper seller and despite looking the same, it was clearly much lower quality. The cheaper watch had a bracelet which was sharp and uncomfortable. Not the case here! The Modsera watch is comfortable and easy to wear!
I got this watch because this is something I wanted Seiko to do but they didn’t and Modsera does it really well. The watch is really well made and feels great to wear. Looking forward to buying more watches in the future.
