Hi All, 

I am new to this forum so hope thsi is OK to post in this section. 

I recent won an ebay auction for a 7A28-7038 and although I am generally happy with the price I paid and the watch I received I would like to make it better in terms of replacing some parts which are either past it or non original.

Firstly the crystal is scratched so I woudl like to replace this. Does anyone know if this is a generic crystal for svereal models or do i need to get on especifically for this model? and where can I buy one? 

Secondly the bracelet, incorrect leather one supplied so I am looking for the steel version with the correct black detailing. 

I have also been informed that the watch should have a full set of white hands but mine has a yellow/orange stop watch hand. 

The Chapter ring is worn from about teh 2 o'clock mark to teh ten o'clock mark? odd but can this be replaced? 

Finally al the pictures on the net show that the inner dials are like a Panda dial however mine are all black? Any information on this woudl be interesting. 

Many thanks for any assistance comments you can make. 

Patrick

Patrick. I have already replied to your previous post in the Everything you always wanted to know about Seiko 7Axx's thread. ;)

Regarding your: I am new to this forum so hope this is OK to post in this section.

There is a forum section further down the main page, where your post would probably have been better suited:

Parts Info, Tech Tips and Tinkering: The place to ask questions; hopefully get some help - and share advice.


 When I get time, I'll merge your two posts (and my replies) and move them there. (Done: Thursday 13th April @ 9:00am).

Here's the content of Patrick's previous post, which has to be said is rather less specific.

Advice needed. This has just landed. I love the model but...this one has issues. Disregard the bracelet as I think this is sorted. The orange hand can be changed as can the crystal (I think) but what I did not see in the sale pictures is the wear to the inner bezel. The markings appear to have rubbed off from quarter passed to quarter too! ??? Can this be replaced? Also orig adds I have seen for this model have a black dial with silver "inner" dials?? Is the black/black orig?

Happy to stick with it and restore but perhaps it's beyond help??

Cheers Patrick

Here's a cut and paste of my previous reply to the above post.

Hi, Patrick.

With the lack of any model number or photos in your post, it's a good job I'm a mind reader, isn't it ? :P

Luckily for you, I remembered seeing this comment that you'd left on your own profile:



It wasn't too difficult to find the recent eBay listing where I presume you bought this watch:


http://www.ebay.co.uk/itm/Seiko-7A28-7038-Working-order-Super-rare-/172597114052


It is indeed 'super rare', because there's no such thing as a 7A28-7038. That model number / suffix doesn't exist. :roll:

Look closely at the model number stamping on your watch's case-back and you'll see that it's actually 7A28-703B.

In fact, if you look again at the eBay seller's description, you'll see he subsequently added an amendment to it:




The 7A28-703B and US market 7A28-7039 have black dials with silver sub-dials, as you correctly stated (in a roundabout way).

I'm sorry to tell you, but the watch you have purchased is a complete Franken - cobbled together from two (or maybe 3) watches.




The very dark blue 703L and orange sweep second hand are from a 7A28-703A (similar model with a Pepsi bezel).

Google images and you'll see what I mean. :/

If you want to try and locate a replacement minute ring, the Seiko p/n for the 7A28-703A is 84304304 and the 7A28-703B / -7039's is 84304305. Both are listed as 'Discontinued', so I wish you luck in finding them.

Same applies to the bracelet(s): p/n B1073S for 7A28-703A and p/n B1074S for the 7A28-703B / -7039.


Personally, I wouldn't bother trying to restore it and recommend you chalk it up to experience. :(

You could try negotiating a partial refund. Either that or return it to the seller for a full refund - I think you'd be within your rights.

So Patrick, presuming you've now read it, my previous reply more or less answered your questions, with the exception of the crystal.


The Seiko p/n for the crystal used in the 7A28-7030 / -703A / -703B and -7039 is 315W16GN00. It is unfortunately discontinued, but occasionally NOS crystals do come up on eBay. I don't have any of these watches myself, but if you were to press out the old crystal and measure it, you'll find it measures 31.5mm diameter by approx. 1.5mm thick, with a polished bevelled edge. If you can't find an original Seiko crystal, you could use one of Cousin's cheap generic mineral glasses as a replacement, e.g. p/n F150CMH315.

I have a Seiko 7A28 7030 which is in fair condition but would benefit from a new crystal so thanks for info.

Can anyone advise me where I may obtain a pusher and spring for the 7A28 7030? Unfortunately one has jumped out somewhere so lost. I am told the part number is 80600529.

Hope someone may help.

We've had another enquiry from someone looking for a p/n 80600529 pusher before. See this thread from a year or so ago.

The position on their availability hasn't changed. However, I mave have spotted something that might be of interest ....

Both to yourself (for a pusher) and the OP, Patrick (for the chapter ring).

It's a dismantled 7A28-7039 watch case listed on Yahoo Japan auctions:

http://page.auctions.yahoo.co.jp/jp/auction/d226480640

Perhaps you could work out something between you.


PS - Before you ask, there don't appear to be any pusher springs in the Japanese seller's photo (close-up photo further down).

The original part number 81350540, that was used on most 7Axx's is obsolete / NLA. Cousins UK have stock of p/n 81351639.

Although forum member BusBoyT2 (Patrick) never bothered to reply to my posts, it looks like he took my last piece of advice and returned that Franken 7A28-704B for a full refund. Because here it is, back again, re-listed yesterday by the same Portuguese eBay seller. The seller may have changed the order of the title wording around and added a new primary image (what was the primary image in the previous listing is now the second), but it's clearly the same watch.


http://www.ebay.co.uk/itm/172663345266


Best avoided at all costs.


PS - to anyone who might be foolhardy enough to bid on this Franken watch again, I'd suggest keeping an eye on the activity of bidder ID j***6 (75), who has currently placed 11 of the 17 bids so far. No great surprise, they featured in the bidding of the previous auction for this watch and have 100% bidding activity with this seller, which clearly indicates a shill.

Caveat Emptor, Gentlemen - especially Newbies.

I really should be making this post in another thread in the eBay section .... this one:

Another example of shill bidding - or just a suspicious pattern ?

Except there really is no question in this case - the auction was blatantly shilled exactly as I'd predicted.

It ended yesterday evening, selling this time for £161 after 44 bids:


http://www.ebay.co.uk/itm/172663345266


To save you counting them, 29 of those 44 bids were placed by the 'mystery' bidder j***6 (now feedback 76). 


http://offer.ebay.co.uk/ws/eBayISAPI.dll?ViewBidderProfile&mode=1&item=172663345266&bidtid=1695943962007



Hopefully that's the last we've seen of it.

Apologies for the lack of response. As you have guessed above the watch was returned and a full refund obtained. Phew.


Many thanks for all the assistance and information, much appreciated.
