My SBDX011 story

I have heard people saying Seiko parts are expensive these days and servicing cost for GS is getting expensive. Here’s my expensive encounter with my SBDX011.

I have a few shrouded divers and I remove the shrouds and clean them regularly. Rust build up in the area covered by the shroud if you don’t clean regularly.

One day, while removing the shroud on my SBDX011, the screw head got damaged (stripped). I sent the watch to Seiko Japan and was quoted JPY160,000. I was told the screw could not be removed and a case change is required. This is pretty expensive. The list price of a brand new SBDX011 is JPY300,000.

In the end, I decided not to do anything about the watch because of the high repair cost.

Here’s a picture of the stripped screw head. Sorry for the poor cellphone shot.

    will e ‘corrosion’ issue happen on SRP227 &/or similar range? coz e range uses a ‘plastic-shroud’… so think will not remove e shroud for regular cleaning…

    Hi yeoman, I have received my screw after 3 months of waiting, and for FYI Thong sia told me the ceramic shroud cost RM1600.. ouch. But to be fair to Seiko, IMHO i think it is better to chance ceramic shroud rather than change the ceramic watch case like IWC top gun model.

    Your concern about rust is very valid. Better to have the shroud removed early. By the time the watch stops working, you may already have a great deal of corrosion inside.

    The piece of rubber between the head of the screw and the tip of the screw driver is good advice. Another method although time consuming will work if the head of the screw is above the shroud. If it is you must hold the watch tightly, clamp it, and use the edge of a nail file or the edge of a very thin file to file a thin furrow in each side of the screw head so a flat bladed screw driver can be used to remove it.

    hi there having the same problem, I just place order for my screw via thong sia and it cost RM 60 per screw.

      I wanted to get the screws from the Japan service centre while my watch was there. My contact person said they don’t sell.

    Hi Thomas, sorry to hear about the issue you’re facing with the shroud screw! It’s frightening to hear that Seiko recommends the replacement of the case! Hope it will work out in the end.

    Did the tuna go sea diving? It’s such a shame that Seiko should at least use better materials to ensure that the case materials were resistant to corrosion from sea water or sweat for that matter. It’s not a cheap watch mind you!

    Best regards always, my friend!


    P.s. Any news when the new Monster will hit the S’pore market? My watch dealer mentioned that it’s close! Much like the General Election date of Malaysia, which is very close too! :-p

      Hi Ian,

      No sea diving but there’s definitely sweat between the shroud and case whenever I wear it. You know how the weather is like here. I’m not sure if there’s any corrosion on my SBDX011’s shroud and case but I have definitely seen rust on that of my SBBN015.

      No news about the new monster yet.

      Best regards,

    Damaged allen head screw. They have a tool with a special head that can remove that screw. I bought a whole set of them for my father a couple years ago for Father’s day. I don’t know the exact name of the tool, but if you follow this link in the picture you will see the tool. The one pictured is for a power tool. However, I know they have hand held ones. Cost is around $7 here in the US. And with it, you should be able to get that stripped allen head out.

    That’s crazy to me that Seiko service is telling you to replace the entire case. I could see maybe if the screw itself was rusted or fused to the case, but it’s just a stripped head.

    Good luck Yeoman. Hope this helps and it all works out for you.

    I thought the case of this watch was made of titanium and the shroud ceramic? Surely there is nothing that could rust?

      My collection of Tunas include the 300m models which have stainless steel case. Also, the back of the SBDX011 says SS/Ti. No ceramic mentioned there.

    That pretty awful expensive watch to maintain. It is as expensive as maintaining a good brand Swiss watch. I wonder other spare parts are cheaper.

    Wow, sorry to hear about that =(

    The watchmaker that repairs my watch has told me that there are tools he can use to remove stripped screws. Since the screw is relatively big and attached to the shroud, rather than on the case or in the movement, I imagine a good watchmaker will have the means to remove it.

    Since you are not going to get it factory serviced by Seiko (I wouldn’t either at that price!), it might be worth a shot. Good luck and keep us posted!

      When I told my friend at Big Time about what happened to my Emperor Tuna, he gave me two options – send it to a local workshop or send it to Seiko Japan. I took the Seiko Japan option thinking this should be a minor issue to them since they must have worked on tonnes of Tunas with this problem since 1975 or earlier. Also, they are able to put in the original screw once the stripped screw is removed. I was disappointed.

      I have yet seek out the local workshop option. Probably not urgent since I could still wear the watch with the stripped screw head.

    Try placing a rubber band over the screw head and then press in with your driver and twist. If you are lucky there may be enough friction to loosen the screw. You can also look in your local hardware store for a screw extractor. Do a google search for finding other ways to remove a stripped screw.

    One damaged screw-head equals to half the price of a 1000M top of the line Seiko diver watch !!! Don’t change it !!!
