[@BigBaz63]

The back in my Promaster is immovable! I have always sent it back to Citizen for new batteries (once a year) but can no longer afford the excessive costs. I usually replace the batteries in most of my watch collection, and have the same removal tool as you, but the back simply refuses to budge and no local watch smiths will touch it. It appears that I now own a very decorative ornament!

[@ScubaMoto]

BigBaz63: Sorry someone over-tightened your case-back. Mine have come back over-tightened and once came back loose. I now service mine exclusively. When mine was over-tightened, I had luck with hot water with mild soap. Fortunately I did not need any solvents (avoid) nor did I need a five point case wrench. It just took some patience. Good luck with yours and thanks for watching and for sharing the comment.

[@BigBaz63]

ScubaMoto. Cheers bud. I may try the hot water route but was unsure what effect it might have on the watch. Mine is the titanium model. It belonged to my father and he wore it on his last dive - unfortunately he did not survive it - so it has great sentimental value. It was the UK Citizen service centre that tightened the back. I am disappointed to say the least that the batteries last so little time in this watch... Just like my Tissots :(

[@ScubaMoto]

BigBaz63: That titanium sounds like a nice one with a strong history. My batteries last maybe one year. I dive at least once a week and dive mode draws a lot more current than just keeping time. If all else fails getting the back off, you could always try JBWelding a very large nut or a large bolt head to the case back. Wait a few days and use a large wrench to unscrew the back. When you're done you can carefully chip off the glue. I've only heard of people having luck with it but I haven't tried it yet. I like it except for the glue removal part.

[@BigBaz63]

ScubaMoto - You are now officially my new hero - for this month at least! I considered your advice and, whilst I didn't like the idea of glue-welding a nut onto the back, I decided to try some differential heating using a medical back warmer for the case and an ice cube in a plastic bag for the back. Still took a lot of effort but... SUCCESS!! Watch is now working again. I no longer dive due to health issues but will need to replace the seal and get hold of some silicon grease, as the threads were far from smooth. Thanks again bro. 👍

[@ScubaMoto]

BigBaz63: That's so great that you were able to rescue your father's watch. Congrats on a job well done and thanks for sharing.

[@DavidMosby]

Great video. I like the narration. I don't understand why others don't talk. Another did not show the silicone grease going on. I wonder if there is any startup sequence for the digital aqualand. This certainly beats paying the watch repair guy.

ScubaMoto Hello SM, where do you buy the correct and original citizen seals from? Really appreciate any answer. I’m having difficulty her in Australia finding it and have a really poor experience with the Citizen dealer with regard to another dive watch. I’m now prepared to just do it myself if i can get hold of the seal/O ring.. cheers Andy

[@ScubaMoto]

@@andrewfleming6487 Although I have found local shops willing to source gaskets for me, I now simply use the dimensions given in the video to order o-rings for my dive watches with great success. Here's a link to 0.8mm gaskets if it helps: amzn.to/3gTEGsd . If the surfaces are clean and properly lubricated, off-brand watch gaskets will suffice. I even order them in large sets of multiple sizes at reasonable costs. These sets are easy to find on-line but you must pay attention to the thickness and ensure that gasket channel surfaces are very clean and silicon grease lubricated. Thanks for the question and for sharing.

Thanks for sharing your video! I have a Hyper Aqualand that is right around 21 years old. Did all dive watches use the same gasket and battery back then that you know of?

[@ScubaMoto]

Chris Pitts: You're welcome, I'm glad you liked the video. They are not all the same but your Hyper Aqualand is the same case back process as this video. I'm not sure of the size so you'll need to verify the gasket. I believe it takes a CR 2025 battery. I have a video on pressure testing if you have a tester. I hope that helps.

[@MrWex002]

hi thanks for the great video! Does the Citizen also have a crown seal and if so have you replaced yours? Any tips on where to purchase other replacement parts like the pressure sensor?

[@ScubaMoto]

I've got four Duplexes of various generations and haven't needed a crown/seal yet. I just lube them with the silicone grease. I thought I saw a new crown with seal recently on Ebay but other than that, I don't have a parts source for these.

[@andresalmozararosende2495]

I need to find a store who sale this o-ring. Citizen in Brazil - all must everything is chaos - it is very dificult to by supplies. Many thanks again !!!!

[@ScubaMoto]

Andres Almozara Rosende: I use measurements to get O-rings which I now buy in bags. Here's a link if it helps: amzn.to/3gTEGsd. Even if you don't find the exact Citizen gasket, you can use the sizes I give, or measure yours and order that size. So long as they are 0.8mm they should be fine. Don['t forget the silicone grease. Good Luck.

[@troyeaston3479]

Hi ScubaMoto. This video seems very helpful! My local watch repair shop quoted me $75.00 to replace the battery because "the watch needed to be pressurized." Is this true? The model of my watch is a Citizen Aqualand Duplex C506

[@ScubaMoto]

Hey Troy, Thanks for watching and for the great comment. This is my preferred method: kzbin.info/www/bejne/d6XNeZycncR5h68 It is good to know the gasket is sealed before diving a watch but use caution in the method you use for waterproofing as some can harm the sensitive depth meters on dive watches. Pressure testing methods is a whole separate topic for a video, and there are plenty of videos on types of pressure tests for watches. I prefer the plunge method as I show in the other video. Please use caution as some pressure tests are useful, others tell you nothing, and some can cause damage to the watch and/or its depth meter. One very well known shop (that I had to mail the watch to) replaced my battery and claimed to have "pressure tested" the watch. When I dove it, it flooded because they left the case back loose. And yet it passed their pressure test? The entire movement had to be replaced (by the shop, of course). A separate local shop that replaced the battery left my Aqualand Duplex watch with error messages after a "pressure test". I was lucky it survived but it needed a complete reset as the test used pressure beyond the design limit of the watch's depth meter. I now do my own battery replacements and tests.

[@roloemam]

Hi scubamoto, great video and you take the rocket science and myth out , which is great. I’ve got an AL0024-06W Citizen Aqualand Promaster watch I bought new and treasured since 1993. Citizen won’t repair it any longer saying spare parts aren’t available. So my first question, what would you recommend to get the battery replaced, surely a standard CR2016 3v like you show in the video, plus a generic 33.6mm x 32mm x 0.8section o’ring like you demo will get it ticking again. My second question to maybe Citizen, why don’t you start making spares again as some of your analogue dive watches from yesterday year still rock and there is a growing market. For those who don’t know the AL0024-06W it’s the slightly smaller supposedly ladies dive watch with luminous green/yellow face. Though many male divers alike have admired this over the gents version and prefer it.

[@ScubaMoto]

That is a beautiful watch BTW. Citizen typically discourages user maintenance (for warranty reasons?). But since they will no longer support that model, perhaps they will share with you the gasket size so you can order your own. If not, then it might be worth it to invest in hiring a reputable watch tech in your location to replace the battery one time and provide you with the measurements of the gasket they use along with the old original gasket and battery for you to catalog for future reference. Most shops will have a vast assortment of case gaskets on hand as replacements. If the gasket channel on the case and case back are well cleaned and greased, a well-sized non-Citizen o-ring should suffice. Good luck with it and thanks for the question.

[@mashcroft3008]

Not sure if you can give any advice, watch works fine apart from not showing altitude and pressure. Battery was changed and not been underwater since. Tried a reset, any advice/ pointers

[@ScubaMoto]

It would have to be a different model since the watch in the video has no altimeter, only a water depth gauge. However, if depth and altitude have stopped displaying the way they once did originally, and the watch is not indicating a low battery (2-second sweep) then you may simply need to have it serviced. Will it manually enter dive mode? Before sending it in for service, I would first remove and check voltage on the new battery. I have received several "New" batteries that were close to 3 volts off the shelf. Even though the batteries are spec'd as 3 volt batteries, 3 volts is actually when things start going wrong. It should really be above 3.20 volts new. Most are over 3.3 volts new. If the voltage is good, a re-install can sometimes reset the mechanism and provide a solution.

Hello sorry to bother you but I have a Citizen Promaster JP3050 55w that need a new battery so when I go to a local watch shop they told me that they well ship the watch to Japan to watch mother company and that well cost me a lot of time and money so do you recommend me to do it by my self or what

[@ScubaMoto]

Omar Almasri: Your watch is essentially the same as the ones in the video. If the shop actually sends your watch to Citizen IN JAPAN, then you will get good workmanship. Citizen IN TOKYO will replace the battery, the o-ring, pressure test it, and probably do everything correctly without damaging anything. They will also perform any other repairs that they discover are needed. If the cost is reasonable, and you are not comfortable and/or do not have the tools to do the job yourself, then that is a safe choice. But it is the same process as in this video.

[@ottohajnal2298]

How many years does a CR2016 battery last without using the side features on the watch?

[@ScubaMoto]

Ottó Hajnal: Mine is very much effected by how much diving I'm doing since dive mode uses a lot of battery power. I rarely get more than 2 years on the dive watches. It's cheap enough and easy enough to do so about every 2 years I'll change the battery.

[@ScubaMoto]

Hey FL P. Thanks for watching and for the comment. You definitely want the right size. Since I don't have an online reference source for Citizen part numbers for all dive watch models, for my Promaster model, I sourced my gasket from a reputable repair shop in my city. I then used its measurements to start buying my own O-rings. Here's a link if it helps: amzn.to/3gTEGsd. Some online watch part dealers even sell the flat gasket type but the round one have worked fine for my annual replacement. Just make sure they are 0.8mm and don't forget the silicone grease. If you can't measure the size of your o-ring, most mall jewelers have a whole rack of o-rings to choose from and could size it for you. Once you know the size needed for your watch model, you can get them online or go back to a local shop. The kit linked above has quite a few sizes including the size shown in the video (32mm).

Sven Oosterom: These watches really don't tell us much regarding error codes so diagnosis can be difficult but I think you are correct. There is likely an issue with your depth gauge. Try this, heat the watch up in very warm water for about ten minutes (certainly not boiling). Just a little warmer than your hot tap water. That has sometimes been known to reset persistent errors. I have had to do this once after a watch shop over-pressurized mine after a new battery install. It's why I now do my own batteries and pressure testing. I hope that helps.

[@lesio333]

Is it worth it to send the watch to the repair shop so they will replace the battery and pressure test it? Or if everything done right, the watch should remain water tight?

[@ScubaMoto]

It's really a personal decision. My preference is to test. Many divers routinely perform battery changes for dive computers without pressure testing. Others insist on professional replacement and testing. If you're very careful and use quality gaskets/o-rings with silicone grease, odds are you'll be fine. But sometimes gaskets fail or o-rings can fail and then it's over. I used to have shops do the testing. After several questionable services, I bought my own tester. My pressure tester cost a fraction of the cost of the watch so it was a pretty easy decision to buy it. A few tests and it paid for itself.

[@lesio333]

@ScubaMoto I do change (many times) battery and gasket in my dive computer myself...... without any issues....🤔

[@ScubaMoto]

The only way to test a parachute is to jump. Fortunately for dive watches, we have pressure testers.

[@lesio333]

@ScubaMoto I was trying to find seal gasket for my D208 Citizen Aqualand watch. Didn't see any. Where do you buy yours?

[@ScubaMoto]

That watch is likely too old to find an OEM Citizen brand gasket. You could call a reputable watch repair shop to find out. I would just measure up the existing gasket and buy my own 0.8mm gaskets (o-rings). With proper installation and silicone grease, the 0.8mm gaskets have always pressure tested well on my watches. I've put links in the video description that should get you started in the right direction for finding the right gaskets. If OEM Citizen brand gaskets still exist for your model, then another way to get one would be to call Citizen customer service and get a price for a battery replacement. Then confirm that they will fit a new Citizen gasket when installing. That way you will get a new battery, a new Citizen gasket, and a pressure test from Citizen for your money.

[@ScoutSniper3124]

What's the value of a watch like this? Thanks

[@ScubaMoto]

Ryan Taylor: The model of the watch in the video is JP1040-09E if you want to search for one. It's the titanium model. You're not likely to find a brand new one but good used ones are about $300 and up. Quite a bit less if you don't want the titanium. The rubber wrist bands are easy to find but the titanium bands are getting harder to find. Citizen later re-launched a similar watch that I believe has the same internals. It has the same dual digital display and the same 4-dive log, but it takes a different band and is not available in titanium. The new model number is JP1060-01Y and there are still some selling brand new.

ScubaMoto so I was trying that and I realized that the crown button is sort of failing, it’s not recognizing the button as being pulled out, I had my wife hold it pulled out and did the three button move and finally it worked! Thanks

s 9: Glad it helped out. Congratulations on a job well done! Thanks for watching and for sharing.

Το ρολόι στο βίντεο είναι ένα Aqualand Duplex, οπότε πρέπει να ρυθμίσετε το χρόνο δύο φορές. Μία φορά για το ψηφιακό και μία φορά για το αναλογικό. Πρώτο Ψηφιακό: Πατήστε το κουμπί πάνω αριστερά του ρολογιού και κρατήστε το για τουλάχιστον δύο δευτερόλεπτα έως ότου αναβοσβήνουν τα δευτερόλεπτα. Πατήστε το κουμπί επάνω δεξιά για να επαναφέρετε τα δευτερόλεπτα στο "00." Πατήστε το κουμπί πάνω αριστερά για να αποθηκεύσετε τη ρύθμιση των δευτερολέπτων και μεταβείτε σε λεπτά. Πατήστε επανειλημμένα το κουμπί επάνω δεξιά για να προωθήσετε τα λεπτά και, στη συνέχεια, πατήστε το κουμπί επάνω αριστερά για να αποθηκεύσετε τη ρύθμιση λεπτών και να αλλάξετε σε ώρες. Επαναλάβετε τη διαδικασία ρύθμισης για ώρες, μήνα, έτος και για εναλλαγή από 12 ώρες σε 24ωρη μορφή. Τώρα αναλογικό: Ξεβιδώστε την κορώνα, ένα κουμπί στην κάτω δεξιά γωνία του ρολογιού. Αυτό σταματά το δεύτερο χέρι στη θέση "0". Γυρίστε την κορώνα για να τοποθετήσετε τα χέρια της ώρας και του λεπτού ένα λεπτό μπροστά από την ψηφιακή ώρα. Πιέστε την κορώνα πίσω στη θέση της όταν η οθόνη ψηφιακών δευτερολέπτων φτάσει στο "0".

@@ScubaMoto vorrei comprare il kit per smontare e le guarnizioni originali hai link funzionante che possa spedire in italia ?

[@ScubaMoto]

Maurizio giasan: Non ho collegamenti ai kit di ricostruzione Citizen originali. Citizen lo controlla. Suggerisco di utilizzare negozi autorizzati locali. A volte ti aiuteranno con le parti. Ho collegamenti nella descrizione del video per le guarnizioni che uso solo per il cambio della batteria. Spero che aiuti.

ciao vorrei chiederti una info ho il mio cotozen promaster c 500 che cambi la pila ogni settimana . eppure il sensore resta spento si attiva solo in presenza di umidità. credo a batterie di scarsa qualità ma non capisco cosa porta ad un consumo .

[@ScubaMoto]

@@mauriziogiasan4411 L'immersione (modalità Dive) consuma molta batteria. Ma anche con immersioni frequenti, dovresti avere almeno 6 mesi con una batteria nuova. Se devi cambiare la batteria ogni settimana, l'orologio ha sicuramente bisogno di assistenza. Spero che aiuti.

Hi sir.. I have one unit of citizen dive promaster C500 - S016070 MST GN-4-S.. now I have a problem because "error" appear. Any advice to solve the problem sir?

[@ScubaMoto]

The moisture detector may have gotten sweat on it. It is often solved by soaking the watch in very warm water for a few minutes, then rinsing thoroughly and then drying it out. I hope that helps.
