    Smile Any info on baby g needed for uni project :)

    Dear all,
    My name is Jamee and i am from Melbourne Australia. I'm ten minutes new to this forum. Im a uni student studying Industrial Design at Swinburne. Currently i am doing a project on a design icon i picked the Baby G Shock watch. I was just wondering if anyone could please help me out with any information they know. What material they are made from? what screws they have? any other speical features.
    There is no infomration at all anywhere on the net so any additional info. would be so greately appreciated and will help heaps.

    jamee :thanks

    Hi Jamee,

    As far as I know is the material used to build Baby-G Polyurethane. As you probably know this material is extreme chemical resist, very hard and strong. Some Baby-G models have a stainless steel case.

    The screws used are the cross heads, pretty common. You can take a look at my Baby-G section on my website. I don't have many, but maybe the pictures help you a bit further.

    I hope this helped you a bit. One of my favorite students last year (Neil will probably remember the bouncing ball project) studies Product Design at the University on Utrecht if I'm correct.

    Good luck on your project. Cheers,

    Sjors

    Hi Jamee,

    Welcome to the G forum.

    I believe Sjors answered some of your questions on materials selection.The polymer used is indeed Polyurethane.Some of the bands uses PUR which is polyurethane rubber,and I have found the grade used in Gs to be extremely durable. Gs do have inner casing & case back made of stainless steel.While Casio did not specifically mentioned the grade of stainless used,I am pretty sure the grade used would be Type 316L.This grade is not the strongest,but it's the toughness of this grade that is desirable.Also,the corrosion resistance of this grade is good,esp. in sea water.You may notice that cheaper version of Casio watches (non-G) tends to rust (corrode) when used in salty condition even though stainless steel is used for the case back.However,the grade of stainless used is different (for cost saving consideration).Also,Type 316L is able to be used in low temperature (i.e. -10C in the case of Baby G).

    I believe certain rare models of BabyG were constructed of titanium/resin (PU).Titanium is half the density of steel,extremely corrosion resistant,non-allergenic,and suitable for cryogenic application.(Frogman is rated to -20 C) Of course,the major drawback would be cost!Titanium is really expensive!


    I hope my explanation of materials would not confuse you.I really like materials engineering.:-D

    Please feel free to post your queries here.I am sure fellow Gs members would be more than happy to assist you in anyway we can.

    Cheers,
    MountainMike

    Re: Any info on baby g needed for uni project :)

    is polyurethane rubber the same as urethane resin? because all the web sites keep saying that these watches are made out of resin?
    thanx, you both don't understadn hyow much you have just helped me out, good fortunate to you both :)

    You are welcome.

    Resin is a generic term.A more appropriate term would be polymer.Polymer consists of thousand of grades,the last time I remembered,a software has a database of 7,000 + grades of polymers (different trade names,grades,etc.).Polyurethane (PU) is just one type of polymers.Polyurethane rubber (PUR) is actually PU with rubber materials added to make it more flexible,you do want your G straps to be comfortable,do you? As mentioned earlier by Sjors,it is the properties of PU that make it such an ideal material for Gs' bezels.:gold

    Other examples of polymer include polyethylene (PE) where it is used to make the garbage bag we use,for example;polycarbonate (PC) is used to make safety glasses,sunglasses,CDs,etc.PTFE(Teflon) is used to make chemical resistant container,etc.

    I have attached a picture that show the parts that made up a G.Note that certain parts are not used in every G (i.e. only exclusive to this particular model).

    Can I just say how truly impressive these replies are...
    I used to list my watches here until I realised it ruined people's Google searches...

    Hi Mike,

    Did you study Polymer Chemistry? It's actually not my speciallity (i did Clinical Chemistry, as specialisation within Biochemistry).

    Hi Jamee,

    I know there is a Baby-G Puppy commercial on the web. I have to do a little search and will sent you the link by pm. I'n not sure I have a picture of a Baby-G apart (yet), but I have a Baby-G destroyed. It was from my sister, who dropped it on the street by accident. This was what she found when a few cars (trucks) ran over it...





    THis is a G-9000 stripped. Several members have parts of this watch, that has been around the world with a friend of mine. He is a surfer and has been in a lot of famous surfspots in the world (Uwe, your back screw is among it). A Baby-G would probably look like it when taken apart. I have to do some repairs tonight, so maybe I have time to strip a Baby-G too. (GMT +2)



    Cheers,

    Sjors

    Hi Jamee -

    Nice to meet you

    First of all, I really envy you being a student as it was a long time ago for meB-)and wish it was still happening!

    I studied at Sydney University.

    What are you studying?

    I'm actually from Sydney but currently living in Cairns.

    I would say the screws are stainless steel, although I am thinking of only a few particular models, namely a "FROGMAN" and "RAYSMAN" G-shock of which I have both.

    I have used both for many years in the saltwater, and their is no signs of rust so this makes me believe the above.

    My wife has a few BABY-G's which she also wear's in saltwater, and none of her screws show any signs of rust.

    She has both metal casing and resin models.

    I have no idea in regards to exact chemical specifications. Sjors and member Neil are both chemical teachers so I'll leave that up to them:-X :-D

    Off to bed up here around 3500KMS away from you and I'm sure a lot warmer, if not dryer

    Hope to see more posts about your Baby-G, and also would love to see a nice photo

    Hi Sjors,

    Actually,I am a graduate in Materials & Manufacturing Engineering.

    Btw,that's a pic of Baby G in a terrible state.I honestly did not expect it to end up that way.Could it be that Baby-Gs are not as tough?:-S The resin looked brittle.What was the year of production for that particular BabyG?


    Hi Ozzie,

    I have good reasons to believe that all Gs use Stainless Steel screws.In the case of Frogman,which has a titanium case back,the inner case must be titanium as well,in order to prevent galvanic corrosion (dissimilar metals is a no-no).The bolts used are titanium as well.I remembered certain Gs,namely the Master of G series,e.g. Fisherman,Frogman all have titanium bits to prevent rusting.

    Stainless steels do rust.It is a common misconception that stainless steel do not rust.Under certain conditions,stainless steel will rust rapidly.Stainless steel gets its corrosion resistance from the formation of a protective layer of Chromium Oxide.

    Casio knows that Gs would be used for diving,hence the grade of stainless used (Type 316L) is selected instead of cheaper Type 304 to ensure better corrosion resistance in sea environment.That's also the reason why you don't see rusting on Gs.

    In Gs manuals,Casio stated that watch with 100m water resist (Non-G of course) should be thoroughly washed and wiped dry after exposure to salt water.This is because of the cheaper grade of Stainless Steel used.Cost saving for non-Gs.


    Cheers,
    MountainMike

    p.s. gettting late,off to bed.It's 0447 (GMT +8).
