The U50 B is a precision instrument for divers and at the same time a bold statement in design. The striking matt-blue dial immediately draws the eye, signalling the highest level of professionalism and underlining the uncompromising functionality of this watch – not least thanks to the white, luminous indices and hands, which provide a perfect contrast. The result: a harmonious overall appearance with outstanding readability.
In true SINN tradition, the U50 B combines well-conceived design with technical excellence: the case and crown are made of high-strength, seawater-resistant submarine steel with the highest non-magnetic quality – a material otherwise reserved for extreme maritime applications. The captive diver’s bezel proves to be especially scratch-resistant, as it has been further hardened with TEGIMENT Technology. A practical detail: the crown is positioned at 4 o’clock to prevent pressure on the back of the hand.
Whether for ambitious dives or as a reliable companion in everyday life, the U50 B excels in every respect, as confirmed by independent testing. Its suitability for underwater use has been verified and certified by an independent institute.
Hi guys and welcome back to the channel. As you can see I'm still over here in Frankfurt,
Germany at Zinn HQ so a massive thank you for allowing me to come in and do these videos.
They've been absolute superstars, they really have. So what we have for you now is the Zinn
U50 Blue and it's just a very cool watch. It's only just been released and obviously you can see
where the U50 got its design cues from. It's basically the same as the U1 Bob is wearing
there but scaled down somewhat and it's made it a lot more accessible now for many people to
actually find it's comfortable on the wrist. I have not particularly large wrists but I personally
prefer the U50 size because after all I own the U15 which is basically the U50 in drag.
It's a lot more kind of um polished up and so forth. I absolutely love that watch.
So anyway if you wanted to purchase this watch and you're based in the UK,
strongly recommend First Class Watches of Hennaworth as they've always got a very good
supply of stock for Zinn. Let's talk sizes. We are talking a 40mm case size. The actual bezel
though is 41mm. The thickness of the watch is a fraction over 11mm. I think it's like 11.1mm.
The lug to lug is 47mm and the strap size on this is 20mm. The cost in Germany on this one as I say
is £2,950. I'm not sure what it will be in the UK yet but overall it looks great. You've got all
the DNA as we say of the U1 with the Lego style hands there and the hour markers and minute track
going around there. It just screams out Zinn. I love the fact that it's got its own identity.
It's not pretending to try and be a Rolex or Maran or anything like that. You can see these
and you instantly know that is a Zinn watch and that kind of makes it a little bit cool.
Minimal script, we've got Zinn U50 automatic and the all-important 500m.
Since this watch is only 11mm thin, 500m of water resistant is a pretty decent and healthy amount.
I'm pretty certain I won't be going anywhere near that in mine. So anyway there you go.
The actual lume I should point out as well is very good in this watch because simple fact is
there is quite a lot of it on those Lego hands and hour markers so it does glow really really well.
Now past that we have got the sapphire crystal. It features AR on both sides. What I mean by AR
is anti-reflective coating so when I turn the watch at certain angles it's almost like the
crystal simply is there. It looks like you can almost pick the hands off the dial. Not that I'd
recommend that but there you go anyway. Now some people will complain that the AR on the front can
become scratched or marked and yes that is possible. The actual sapphire crystal itself,
very hard to scratch. It is possible but it is very very hard to do. It will take an awful
amount to actually scratch one but the AR coating can be scratched. If that is the case you can
always take it to a professional watchmaker like myself or someone else who can remove it for you
or you can actually remove it yourself. I have done a video on how to do that.
The bezel is a tagmented bezel on this. It also features actually like recessed parts for the
numbers there. So on some bezels you do find from other companies eventually the actual
painting rubs away but being that this is recessed in it will last an awful amount longer. You also
have the lume pip up there. When it actually comes to the action of the bezel, 60 click,
nice muted sound, back plate, yeah there is, it does click back some but that's part of the charm
of it I think. There you go, that locates in perfectly at the top there. It does feature
the captive bezel system so if you were to bash this, you know if you were actually using it
for swimming, you bash it against some coral, you could actually, you know, on say a watch like a
Rolex or a Seiko or something like that, you could knock the actual bezel off. This one has
a retaining ring all the way around the movement and to remove this all you have to do is back off
a little bit these screws here down to here, not at the 12 o'clock and then you can just remove it.
It makes it so much easier. I really like it because it means if you were to have to remove
the AR you could take this crystal off, the bezel off, it wouldn't be a problem.
The case of the watch is a nice simple affair. I like the fact that you have drilled lugs here
so what that means it's much easier to take the actual strap off. If you have a bezel tool,
normally you'd have to go in from the back and prise the spring bar back but when you got it
in there you can just push it through and pull it off. It makes it a lot easier to work with.
Now the crown is over at just on the four o'clock position. They have actually machined in a flat
there to make it sit a little bit better. Now this helps in stopping the watch, the actual
crown from pressing on the back of your hand. It also protects it a little bit more in case of any
kind of impacts because it's lower down here and is protected by the actual lug of the watch,
the case. It is a little bit oversized and it is a screw-down crown as you can see there.
Let's see how it unscrews. That's it. So that, that's it's just popped. So that is now hand
wind. Let's actually move the hand that way, push it back in again. So hand wind, next click,
that is your date change as you can see there and then full out there and that's into your time set
or where it hacks the second hand to stop it there. Then screw that in and it goes in nice
and positive, no problems. Now on the back we do have a solid case back but underneath there we
have the SW300. Now Zinn only use top spec movements for their watches so not to be mixed
up with say some lesser watches which have an SW300 movement as there are four different grades
of movement and there is a quite a difference between them so they use top grade movements.
The only one above that is chronometer spec but to be fair Zinn regulate all their watches in-house
to that kind of spec anyway. So I did put this one on the time grapher and it was coming in,
I think it was at plus 1.5 seconds so testimony to how Zinn actually regulate their movements
whilst they're in the back of the watch. You would think that everyone does that but that's not the
case. Most people regulate the watch movement before they even get to case the watch and then
you might find that harmonics due to it being cased up can change. Normally on many movements
if you say have an amplitude of 260 or even say 270 when you put the auto module on the back you'll
find it will probably climb then when you put it in the case of the you know in its actual case
you'll probably find it will climb more then again which can then alter the daily rate of the actual
watch. So it's nice that they actually do it while it's in there and they always do it to zero to
plus eight seconds. Now the strap on this one they've gone for the full textile blue strap to
kind of match that dial and it's to be fair it is a really solid strap. You have on this side
a full b-blasted pin and collar on there pin and collar sorry the buckle on there and it has two
keepers. This one's fixed I cannot move and this one is a floating keeper. Let me put it on my
wrist so you've got an idea how it looks. Quick wrist check first I am wearing my Zinn U1 which
is a bit of a classic now and as we've said Bob has gone for the U sorry EZM1 not U1. Bob has
gone for the U1 there. So let's put this on my wrist my wrist size is seven and a quarter inches
that works out to about 18.5 centimeters. So let's put this on it's a little bit stiff at first
because obviously this is a brand new strap and there you go that is it on my wrist there. It's
just I think the perfect size they really are very very cool. Anyway let me know what you think this
one in the comments chaps but most importantly you all stay safe out there. Take care. Bye!
