My new Darth Tuna SBBN 013 suffered some battle damage. I wish I could say I damaged it diving a wreck in Tahiti or cave diving in Yucatan or something dramatic! Instead, it was damaged during activities of daily life. Unfortunately I knocked it off the counter in the bathroom and it fell on the stone tile floor. The ceramic shroud cracked and a section is no longer there. I emailed Mr. Higuchi to see if I can order a new shroud, we'll see what he says.


I guess the ceramic lasts longer then the plastic shrouds (e.g. on the Arnies), but the point impact really did it in. Maybe I can wear it as is, a little wabi never hurt anyone right?...a little "imperfection" or "weathering." Anyhows, here's the damage!

Sorry to hear that :'( - but I am not so surprised - just like sapphire, ceramic is tough against small scratches but is not elastic at all and 'cracks' :(

Ouch...sorry to hear that...I dropped a watch with a ceramic coating on a ceramic floor a few years ago. The noise made at impact was horrible. I cringed when I picked the watch up, the fall put a tiny crater in the coating.

Not a good feeling.

I really share your sorrow - not a nice sight.

However what can we learn from that ?

The shroud should be a protective device. If it was
the SBBN007 Stainless steel shroud or Titanium made shroud, this
would not happen to you.

Means Seiko chose the wrong material for the shroud, for
a high end watch !

Something for us (and Seiko) to think (and discus) about.

sorry to see that , my friend


hope you can get the replacement soon...

it makes me wonder
what happen to the trend of many brand , to make dive watch as a luxurious expensive bling2 product ?

watch with ceramic like Darth, Rolex new sub, all the BP fifty fathom ceramic, etc

even my MM300 (not ceramic but too shiny bling in the bezel) makes me
uncomfortable when wearing it,
i keep checking and baby my wrist
coz afraid of ruin the beauty shiny bezel

....
dive watch now so expensive but not so wearable (in term of freedom and not worry wear style)

Ceramic is scratch resistant but brittle. I cringed when I saw it used in a watch that way. I think Seiko should had installed an oring in between the case and the shroud and also on each of the retaining screws so that it actually 'floats'. It should save it from impact damage more than a rigid install.
Sorry to hear about your watch.

I heard stories about broken shrouds, but always thought it was nearly impossible untill you use the Tuna can as a hammer :-[
Well, it is possible :-\
Looking at the pictures it makes me cringe.

Like 5seikos already mentioned. The ceramic SBBN011/13 and SBDX011 shrouds are more scratchresistant as the normal steel ones of the SBBN001/015/017 but are so hard they break.
Seen this also on a few Rado watches, the complete watchcase breaks when dropped.

I have a lot of shrouds in stock except these as they are horrible expensive...almost the price of a used watch. Btw the shroud of the older 7549-7009 will also fit. These are steel covered in ceramic coating. The coating can chip but the shroud will be intact.

While it is bad luck, there are several silver linings. Firstly, it's a clean break that from what I can see in the pics didn't mark the case. A shard of ceramic could have easily left gouges in the titanium. The watch could also have bounced in such a way as to mark up the bezel, the case, crown or bezel insert after it hit the shroud. It seems to not have. Even the screws could have been scratched. All in all, the shroud did it's job and did it admirably.

I disagree with the above post that Ceramic was a bad choice of material. So what if steel would not have shattered? An impact that shattered hardened ceramic would most likely leave steel deformed and scratched, which given this is mostly treated as a dress watch would still get replaced anyway. Ceramic is virtually immune to scratches and frankly should only shatter given unrealistically hard impacts, or unusually hard surfaces. As someone else suggested, you either have to hit it with a hammer, or drop it on something very, very hard. In this case a stone floor.

Nobody can be happy when having to pay damages, but you can always be appreciative that it's a protective piece of equipment that protected your watch from severe damage. It just got sacrificed in the process. Frankly I'd be happy. Don't let little cosmetic misshaps ruin your enjoyment of a fantastic watch.

So sorry with what happened to you but I fully agree that it's the purpose of the shroud.
It was meant to be protective device; should it not break, the watch would have been damaged worse.
At least, it proves that Seiko did the homework and applied it accordingly on its product.

:iagree: Sucks that it happened, but I agree with Kucimo. The shroud was designed to absorb the shock. Much like the foam inside of a car bumper, and if it absorbs enough shock it must be replaced. But the insides of the watch continue to function as normal, and that is the point.

That's gonna be spendy...hope Santa was good to you this year. ;D ---A

I am terribly sorry to see what happened to your Tuna.

I must disagree with some people here. IMO, this is absolutely a design failure on SEIKO part.

First, it is a rule of thumb to use ductile material to absorb impact energy. Anyone with understanding about stress-strain diagram of material can confirm this. Therefore, SEIKO decision to use brittle ceramic for shroud material to absorb impact and protect the watch must be brought under questioning.

Second, take a look at the ceramic debris and imagine how it can easily puncture or slice the wearer's wrist when he/she has accident.
