This 300m water-resistant dive watch is incredibly reliable, with its screw-down crown and precise unidirectional bezel. The bgw9 lume is brilliantly bright. Paired with the scratch-resistant ceramic bezel and an included silicone strap, it’s an absolute steal!

After 8 days the watch came from germany to romania(carrier came by foot) and receive the package in this morning.
The box in nice and minimalist, spare silicone strap, a mini device to adjust bracelet.
Quick remove the metal bracelet wich is very qualitative, with micro adhustament, no sharp edges has brushed and polished lines and remove 3 links easily…done.
The watch….well it’s very well made, a little bit heavy and thick compared with my 1980 citizen automatic(only 10mm thick) but as a diver is very well finishing making it wearable day to day and occasions too.
I’m happy with the gradient blue dial, beautiful wich under light is brightfull blue, the bezel works great, alliagned perfect to 12, screw crown, 1st position i winded manually +40 times, 2nd position change the date, 3th adjust time…and ready to go!
The movement is tmi nh34a, look nice from behind, make a measurment and has 8 seconds/day error and 251 amplitude, is it good?
Over all i’m very happy, totally recomend

Honestly, I am amazed. A very beautiful watch that has really high quality. The time is accurate and it doesn’t run late; the Seiko movement works very well. Rated for 4 days! The GMT hand also works perfectly. A sporty silicone strap is included as an extra. If it’s really as waterproof as the seller claims, why buy a Seiko that costs 4 times more!? It’s a great deal!! Plus, it was delivered in less than 4 days in France. Go for it!
