Let customers speak for us
from 92 reviews
I ordered în total 5 pieces from Sillvento. Before reciving the whatces i was i little afraid about the quality , but in I ordered 5 pieces from the sillwento website. At first I was a little skeptical about the quality of the watches. But to my surprise the products are really of quality and look exactly like the pictures on the website. I must admit that I waited between 10-15 days to receive the package but it was worth it.
Marvellous
A beautiful watch for any occasion. Elegant, cheerful, and beautifully finished, it has it all!
Thanks for your good job.
The SILLDAY Tiffany Blue MOD watch perfectly blends elegance with modern style. Its Tiffany Blue color adds a refined and distinctive touch that instantly catches the eye, while the minimalist design and quality craftsmanship show great attention to detail. The strap is comfortable and durable, and the movement runs smoothly and accurately. A timeless accessory — simple, sophisticated, and full of class. ⌚💎

This watch is one of the best looking watches in my collection it is a stunning mod and I would highly recommend it to anyone. The customer service was excellent too. I definitely will be making more purchases in the future.
Good communication with the seller.
Fast shipping.
Everything, including accessories and costs, were exactly as stated.
Most importantly, the watch looks great.
The watch is absolutely stunning, even more beautiful in real life than in the pictures. The quality is impressive, every detail is elegant, and it truly stands out on the wrist.
Service was smooth, fast, and very professional, which made the whole experience even better. I couldn’t be happier with this purchase and highly recommend it.
Warm greetings from Italy 🇮🇹
Recently received this watch and was thrilled with the craftsmanship. Within a day people were complementing on it....
My issue is that I am already looking to purchase another sooner than I thought.
I bought it along with a skeleton, and both were a success, but the elegance of this model is incredible. The packaging is careful and perfect, and the follow-up with Sillvento inspires great confidence.
I got this watch around a week ago FYI. But it took a lot of time deciding which watch to get. I really was worried about how this seiko mods will turn out and how lasting they are going to be. I asked for a lot of help and information on IG where I have gotten thoughtful information fast about everything from sizes, bracelet change and real life photos. I even asked to change the original bracelet, which they did for no additional costs (thanks for that again!). Then I got the watch (size 36) and it just fits me perfectly, I do recommend to most of the others that have a medium to large wrist to get the bigger one, first I thought its to small for even to me but its great. I needed to remove the links myself which was easy after a quick google search since I got the tools necessary in the box included. The watch looks perfect, even better to my surprise than on the website.
I'm a creator who is in collaboration with sillvento and i cant honestly say that i'm so impressed. It's better in person than on photos. The quality and weight is spot on, it looks stunning and you can tell they put effort into their work!
Well done guys!
The support is very helpful and the clock looks great
Its a beautiful, solid watch and i think that is better than i expected.i wish to order a second 1.thanks guys .
The craftsmanship of the watch is excellent,the delivery was fast,
