When is a diving watch no longer a diving watch?


Recommended Posts

Hi all, am needing some advice.

As everyone probably already knows here as soon as you mention you are interested in watches friends and relatives say they have a watch in a drawer that doesn’t work and could you possiblyhave a look at it? 🙂

Well this happened to me last month when a relative said they had a Citizen Promaster Aqualand (5810-F80014 TA GN-4-S) diving watch they bought whilst working in Asia 30 years ago that doesn’t work and  has been in said drawer for 15 years. (See pictures below).

Even though I am more interested in antique watches from the early 1900’s than quartz diving watches I agreed to have a look at it and after purchasing the appropriate tool to remove the screw back replaced the battery which had no effect initially until I read online the pressing all three function buttons simultaneously can re initialise it and it duly sprang into life!

As you can imagine I was very pleased with myself that I had managed to get it going and after cleaning it even re-enamelled the bezel as the paint had started to come off after watching an excellent video by Mike on his “My Retro Watches” channel on how to do this.

The problem came when I went to hand it back to my relative, they were so grateful and told me it was perfect timing as they were returning to Asia in December for a once in a lifetime 3 month tour and were looking forward to taking it diving again!!!

Now I am no expert, and I did treat the case back washer with some sealing grease before reassembling, but being that this watch is from the early 90’s I’m guessing that some of the gaskets may have perished and need replacing and the watch will have to at least be pressure tested before going back in the water.

After making some inquiries I have been told that vintage Citizens can be difficult to reseal and presure test and manufactures don’t even recommend taking vintage diving watches in the water if they are more than 20 years old. I did e-mail Citizen UK but they just sent me a returns label without any discussion on whether it is possible or the cost which didn't inspire confidence and after reading some horror stories online about Citizen Customer service I am loathed to send it off into possible oblivion given that it means so much to my relative.

Does anyone know of a good watchmaker that may specialise in diving watches who could make it useable again (assuming gasket kits are still available) or is this watch destined to be no more than for show and never see the sea again?

Any help from the knowledgeable inhabitants of this forum would be very helpful indeed!

Many thanks in advance

Adam.

Yes, a diving watch is theoretically a piece of life safety equipment.  It shouldn't be dusted off and wound just before you get in the water.  I don't dive but,  like most hobbies, it can't be cheap.  As a percentage of the whole trip, how much would it be to have it served properly (take no offense, I wouldn't "certify" it sea worthy either).  A dive shop may know someone, after all, their all in the same boat.  Pun intended. 😊

Good luck.

When do you change gaskets as opposed to just relube and reuse? Anything to look out for? Rule of thumb as regards its age?

Or with a diver, is it change as standard procedure?

    • This was in a vertical position. Like in the short gif video. Amplitude is fine across all positions, at full wind and after 24h. I could post tons of pictures, but please take my word for it.    It was advertised as running fine and my friend was surprised that it didn't. The seller has a very good reputation on Chrono24, so I doubt that it's an intentional pass-on of problems. He responded quickly offering to take it back (and paying for all shipping) or reimburse 300Eur for a local service. If the problem is what I/we think it is, then the latter is a good offer for ~1h of work and a 50-100 Eur spare part. 
    • if it's a serial number it's not a very unique serial number. It is probably more likely and what it looks like is a casing number. then searching for that we do get better pictures at the link below. https://www.ebay.co.uk/itm/224410066581  
    • hi watchweasol,  I probably called it by the wrong name, I called it jumpstart but I think its just shorting I have posted my query in the safezone forum I am hoping its a simple fix, otherwise its sending to seiko to fix. thanks from England voith  
    • watch repair is all about practicing
    • what happened to the old spring? according to the website below no parts are available but they do give a mainspring listing not sizes unfortunately. Then taking that number to the home page looks like it's available cheaper than eBay. http://cgi.julesborel.com/cgi-bin/matcgi2?ref=PP_10-200 http://www.julesborel.com/s.nl/it.A/id.27029/.f because I was curious about the number I found up above I looked at bestfit online. Here's what I found out that looks like it's the right number unfortunately because it's an original spring we don't get any dimensions.
