Just looking for input from People who know these watches well please.
Selling this for a friend Soon who has owned it a long time and when I list it I want to make sure I’m getting it right. No PMs to buy please.
From my observations it looks all original.
The crown, glass, hands, dial and bezel.
Have I missed anything?
Thanks for your help.
Cheers, Michael

Did you run the serial and check that it’s correct for a resist dial? Did you check to see if a resist dial needs a resist caseback?

hint: google “seiko date finder”

bezel insert does not appear to match the condition of the watch. You need to document that.

I would love to find out it's in amazing 100% original condition but as pointed out above, there are certain components that look like they were made yesterday. If that watch is in fact the real deal then it's about the best original dial and hand set I've ever seen, and after 15 years in the Philippines I've seen a lot of them.

I’m very curious if the serial fits into the proof age... I thought almost all of these are proof dials not resist dials. But I’ve been wrong.

Thanks for the reply.
The serial dates the watch to 1976 as far as I can see and both resist dial and resist case back seem to be the norm on these watches from 76, or the ones that I have seen.
The bezel looks like it is original, are you saying it isn't or are you saying it just looks like an original bezel insert but one which has been replaced?

Thanks, Michael

Well there's not much wrong with replacing an original part with a genuine better condition part. Like I said I hope the watch is the real deal and simply well preserved.

Proof/Proof were 1st year (1970). This looks correct to me, resist/resist with short seconds hand correct for '76. Bezel correct imo. Nice watch.

It is certainly one of the hardest watches that I have photographed due to the glass reflections, I can usually get it right but with this watch it has been a challenge.
The dial and its lume is perfect, the hands have a little bit of darkening.
The owner was not aware of its collectability.
Cheers, Michael

She certainly is a beauty and I would expect you will be able to get top dollar.

Looks very nice overall. I think resist/resist is correct for 76. Just looking at it, I would wonder if the sweep hand is a replacement since it appears to show substantially less wear and fading than the other hands (including lume, especially red). UV test might be definitive. You also want to check that the crown lock is operational.

The crown lock is fine, I tested that and all is well.
The lume is also good.
Here is a test I did just now. Around 13 secs From start to finish. The second hand is probably the dullest of the hands, also the bezel pip is quite dull.
Thanks, Michael

Nice watch. Would love to add to the collection 😉

The transition from PROOF to RESIST was mostly finished by 1971 and as this example is towards the end of the production run RESIST/RESIST is correct for a 1976 model.

The case looks to be in pretty good condition with the brushing still visible on the top and bottom of the case and not many dents/scratches visible suggesting the watch was looked after and that the bezel insert may have not seen too many knocks.

I could not see a side profile to gauge whether crystal is flush or protrudes from bezel.

Dial and handset look OK to me.

The movement should be a 6105b which hacks but cannot be manually wound.

Out of interest was the pressure test conducted after a recent replacement of seals?

Hi.
The glass protrudes probably 0.4mm over the bezel.
The 6105B movement is hacking without manual wind.
The gaskets were not touched, I only asked that the movement was serviced, my watch guy pressure tested it anyway with the above results.

All the best, Michael

Doesn't the fact that it glows when it's not under the black light mean it's a relume? The original tritium would have stopped glowing by now. Perhaps that explains why the dial looks so fresh?

Not that that's the end of the world or anything if that's true. I had my 6105 relumed and it's a better watch now

I’m confused. You’re selling it for a friend but don’t want any offers to buy?

I've seen a good few 6105s - and owned a few - and this looks to be a very nice and correct example. I doubt very much that it's a relume. Many of the photos show washed out white lume, but the closer ones from a slight angle show the creamy tinge and perfect filling of the plots. Dial and hands also match.
If I was bidding I'd have no hesitation, but you may want to take better photos for a listing to better illustrate the lume colour.

Welcome to magic seiko tritium. It holds a decent glow like luminova.

I’ve got a 68 that does the same thing.

Here’s another... I used to collect these about 20 years ago. All original condition.

The watch in question looks good.

I'm trying to remember the keys to locating a fake 6105
1. Crown... fake have only 5 teeth in each section
2. Date Wheel surround window has sharp edges on fake dial, more rounded in authentic
3. Hands on fake don't have beveled edges and are more rounded on tips
4. Bezel does not have grainy finish, but rather shiny on a fake
5. Dial lume tends to be more greenish in color, the lume markers edges are rounded in a fake

What have I missed... it's been awhile. But, the OP's watch looks good from what I can see.
