    Afternoon all,
    An old friend returned home the other day. A Seiko wrist watch I purchased in about 1996 and foolishly sold ended up with at the home of my favorite gunsmith. I saw it and it took me a few weeks to remember what it was. He was good enough to sell it to me and it is now in the drawer with several others. I enjoy bells and whistles at times and this one has a few. I think I will enjoy wearing it when I need to dress up a bit. I bought a very nice Caravelle just after Christmas so it must be my year for new time pieces. Anything anyone can tell me about it is appreciated. When I bought it I knew nothing about these things and of course still don't know much. I hope to attach a few photos to this. Thanks.

    The most important information is printed at the 6 on the dial or on the back of the watch there should be a number xxxx-xxxx.

    Looks to be a later quartz model but cannot be sure which Seiko it is wthout being able to read the case number or dial number.

    A faux quartz dive watch. Dont let it get wet as that 100m rating means you dont want to get within 100 meters of water... ;)

    7T is Seiko's faux chronograph and I agree about the stay 100m away from water comment.

    The serial # on this watch is 720466. It also claims to be water resistant to 10 bars and has the number 7T62-OHAO also on the back. I felt bad about not getting a good image on the face at 6 o'clock position until I saw how small it is but it has the same inscription. Dang small, it took a magnifying glass and then I could barely read it. What is a chronograph, in what way does it differentiate from a watch? All the timers and buttons I guess. I bought it at the time because I thought it was really cool but there is no way it will ever go in the water, not on purpose anyway. I have other watches for that kind of thing, mostly those that claim to be water resistant but cost about $25. I don't wear anything like that in a salt water environment. I can tell now that I'll probably always have plenty of watches that I like but may never have a high end watch. I recall having a Tag at one time but someone relieved me of it without permission. Anyway....

    You don't even need to know what a dictionary is. You only need google or that's what they may or may not have sucked you into believing.

    What most people don't comprehend is that a pressure test is another thing to being within a metre from a garden hose.

    The commonest response from those who'd never wear it in water when asked but do you wear it in the shower?

    was, yes.

    The worst was that most didn't comprehend the actual functionality of a screw down crown
    or indeed why it actually had to be screwed down properly.

    The mark: 7T62, indicates the movement -
    OHAO, indicates data about the case and band.
    The number at 6 on the dial is actually the dial number but it does incorporate parts of the other numbers mentioned above.

    An annoying thing about quartz chronographs is that when they come in for batteries, the chronograph hand/s are never synchronised. ie: they don't return to their original positions.
    The only way to fix this is to manually return them. Which means removing the movement from the case to do so. In the 7T models, this can be a risky business. In fact if they come in with the stem damaged. Don't try to fix it. Get a new movement. This is probably good advice for quite a few of the modern quartz watches.

    I paid a whopping 8 dollars for a water resistant quartz watch, with a screw back case, its been in water often, no problems. And no screw down crown either.

    Define, in water and have you opened it to see if water has or has not actually entered?

    Beware that this may not always be the magic you have experienced. Many chemicals take their time breaking down the seals.
    If you do want your watch to remain as from the factory, you should replace all seals on an annual basis if you wish the factory warranty to be read correctly.


    and again from above,

    No there is a procedure to reset the hands on these, absolutely no need to pull the movement, lift the hands and reset them, read the instruction manual, basically the crown is pulled to the hand set position, then it's a combination of pressing the A and B buttons to reset the hands, some models need to have the AC cleared after a battery change to make sure the processor is reset, then various combinations of buttons to reset the hands, they are just servo motors and movement needs to know where the hands are, it's not a hardwear setup like on a mechanical chronograph.

    For example on the 7T62, pull the crown to the hand set position (second click) press and hold the upper button A for 2 seconds until the seconds recorder turns a full circle of the dial, then use the lower button B to reset the hand, once done then hold button A until the minute recorder hand does a full circle, then use button B to reset it, then set the time and press the crown back in.

    That's always been an annoyance of mine, there is no such thing as waterproof, water resistance, I used to service the cases on Seiko sports 100s, a 4 button LCD watch that the surfers would wear year round in the surf, and every two years they come in for a battery and pressure test, by then the push buttons would be frozen or very hard to press in, clean the case and buttons, regrease the seals new battery and watch would be fine for another two years.

    A 100 metre watch with a screw crown is fine for daily use and it will resist pressure from a hose, not every 100M watch has screw crowns so care is needed if hosing the garden or washing the car.

    Current Rolex owners I find particularly annoying, brainless most them, because they assume, I have an 18ct Rolex President in at the moment, the owner was on a boat trip, went swimming in the onboard pool, watch filled with water, two weeks later he brings it for repair........

    Yeah, it's about as bad as you can imagine, the only useable parts are the brass plates, the jewels and hour wheel, every​ steel part is rusted out, the escape and forth wheel pinions are non existent, all the screws, setting etc etc,.


    But what does really annoy me is these phone companies declaring their phones are waterproof, yeah only to a metre, do 30 metre and they'll leak, so they are not "waterproof" are they.

    You didn't quite grok my comment. Yes, doing button combo things according to instructions gets the hands spinning around but it will always go back to the wrong spot. I didn't mean removing hands but I did mean taking the movement out of the case and manually moving the hands to their correct positions. After which all the fancy button magic does drag the hands back to the correct positions.

    I'll be happy for you to tell me a different way but the watchmaker who retired and allowed me to get back to work, used to work at Seiko Service centre and he used to pull his hair out trying to set the hands until he asked his former friends from Seiko. The hands will go back to zero if you push them there with your tweezers. This has to be done every time they get out of synch. It is what has to be done with all these faux chronograph quartz watches.

    I'm going to have to dredge my memory or use google to get the dates but back in the day there was a landmark court case whereby it was proven that even high quality stainless steel is porous and that rubber seals don't last forever so from that moment on which was probably around the time that NASA was preparing to go to the moon. The finding was that the word/s water and proof should not be in the same word or sentence legally. Which is why ever since then the ones who attempt to be legal have always used "water resistant".

    Yes it was something to do with that, from that point watch manufactures were not allowed to use the term "waterproof" which is why it annoys me when I see phone manufactures advertising their phones as waterproof.

    Whilst is is true that there are cameras that are specifically designed to be used underwater, everytime the hatch is opened it needs to be done properly or the camera will get water in it.
