Insert insanity 6309 bezel inserts

The 6309, 7548, 7002 bezel insert topic has been driving me crazy since I started collecting these divers.

After reading through many posts on the topic I thought I had it sorted out until a few days ago on the "what are you wearing thread" a member posted a 7548 which lead to a discussion and their observation about the inserts.

Before reading his comment I was under the impression all 6309/6-704x and 7458 black diver inserts had a matte dimpled appearance.

I thought the 7002 divers had the black gloss inserts with a greener lume pip.

The member in the "what are you wearing thread" had observed that around mid 1981 the bezel inserts in the 6309 and 7548 divers started to be seen with the black gloss finish.

I went through my limited diver collection and observed the following:

6309 September 77 matte
6306 March 78 matte
6309 August 79 matte
7548 January 80 matte
6309 January 81 matte
6309 March 84 matte
7548 (200m) August 84 gloss

My recently acquired 6309 from March 1984 has a matte insert where maybe it should be gloss.

Looking at pictures on the internet they are often too low in resolution to pick up the texture on the insert.

I was hoping when members had a chance if they could have a look at their inserts and post the reference, month and year along with whether their inserts are gloss or matte.

Also if they had made their own observations on this subject.

Any 6309-7290 and 7002 (150m) inserts also.

Many thanks in advance.

I was that member you were referring to :)

I'll start by saying all the watches I'm outlining below are original examples from what I can tell, I have no reason to believe their inserts have been replaced, but I can't 100% say that's true because I'm not the original owner of any of them.

That said, what I have seen from my collection, the net is - for 6105, 6306/6309, 7548, 7C43, 7002 full size divers - '70-early '81(March) have matte bezel inserts, mid '81 (June?) and on, have gloss inserts.

From my examples of 6306/6309-70XX - they are all matte bezel inserts (Dec '77 - March '81)

From my 7548-70XX examples - they are matte bezel inserts (Mar '78-Dec '80), with my June '81 (orange dial) and June '85 (200m dial) examples having gloss bezel inserts

My 7002-70XX examples - they are gloss inserts ('88 - '89) - the pepsi doesn't look like it in the picture, but there is a gloss sheen on it when looking closely. All the 7002's I've owned have gloss inserts.

My 7C43-70XX examples (2 SQ variants since sold) were gloss inserts (Both from '87), and my JDM 7C43-7010 from '91 also has a gloss insert. All the 7C43's I've owned have gloss inserts.

I'll caveat with the usual saying - you never know with Seiko - I'm sure there are outliers, but the above is what I have seen with my collection over the years.
