Fundamentally, the materials and workmanship are of a high standard and offer no cause for complaint. Even as delivered, the watch has a maximum rate deviation of 2-3 seconds per day (depending on wear), which truly corresponds to swiss chronometer values! It can be assumed that the movement (nh35a) was specially regulated before sale/shipment. This is highly commendable! The lume is plentiful and absolutely phenomenal! Even in slightly dim daylight, it shows through, making the watch incredibly easy to read. Just right for someone who is semi-blind like me! Robust, reliable, accurate, and perfectly legible… you can’t ask for more! Definitely worth every cent (and much more)!

Great watch for the price! Nicely finished and weighty–it looks and feels like a quality, much more expensive watch. The leather strap is much better quality than i’d expected. It really looks nice. I’d worried about the size as i have a deep blue watch with identical dimensions that i rarely wear because it’s so bulky, but this one somehow seems more reasonable and proportioned. The blue lume looks nice, but it’s not as bright nor as long-lasting as some reviews of the watch have claimed–but, again, for the low price, it’s quite good. Just don’t expect it to outshine a much more expensive watch. I’ll be wearing this regularly and happily.

Really well done homage to the u1. This is a hefty dive watch but it is amazingly comfortable and well balanced on my 7.3” wrist. Lume coverage and longevity is excellent. The bezel alignment is good and moves freely, but the clicks could be slightly more “confident”. The movement, as expected, is smooth and accurate. Even the leather band quality is quite good. An amazing offering at this price point!

Very chunky watch, i like the big size and weight. Quality is good, bead blasted steel feels and looks nice, it’s not a scratch magnet. It’s a very nice sinn homage, good lume but but excelent. The bezel has nice clicks and alignment is good. Accuracy is good, +5sec/day. Bracelet is ok, i’ve had similar, nothing to complain about. Overall very satisfied with the purchase, highly recommended!

For the price this watch is more than enough. It is not as big and heavy as i thought it would be, and looking like a much more expensive watch. The lume seems very good and overall i would recommend it.

Excellent seller and fast shipping. The hands are set correctly, the
Bezel snaps in cleanly and does not wobble. And very rare in this price
Range, a metal retaining ring and two seals. One disadvantage, however,
Is the offset labeling on the bezel from the 4 o’clock position to the
9 o’clock position.the luminosity of the hands and dial is very good and
Lasts a long time. Overall, however, the watch is worth the price.

Very beautiful automatic watch, arrived extremely quickly, the watch is very beautiful with a very sturdy strap that is easy to fasten to the wrist, screw-down crown, waterproof to 20ATM, there are other strap colors available on the website, I ordered it in black for a more stylish effect.
Recommended purchase despite the price, but the quality is very good. 👍 👍

Perfect homage. Nice and weighty if you like that sort of thing. The engineer bracelet is a nice touch. Quality is evident. Bezel action, perfect. Screw down crown, perfect. About *3 sec on the timegrapher.
