This will seem like a whacked out idea -reviewing a 33 year old watch- but I have my reasons. Many see these vintage divers posted and wonder what it is like to wear or how it stacks up to a current model in size or wearability.

For anyone wondering here is my impressions of this 6105. Now, bear in mind that this is an IWW restored example so while not "museum" quality it is a very nice wearable watch.

The 6105-8110 is 44mm in width without the crown. This is a very good sized watch. No, it is not the monster sized 47mm-50mm watches that are out there but it is more than large enough to have great wrist presence and yet be comfortable.

The unique asymetrical case and crown guard help add to the visual presence of size without making the watch unwieldy. The watch with crown/crown guard is 48mm:

The "lug to lug" measurement is 48mm as well so large enough for my 8" wrists but probably small enough to fit comfortably on smaller wrists as well:

At 13mm thick it is the perfect thickness to fit under any shirt sleeve:

One thing that those used to modern divers will notice is the unusual 19mm lug width. This makes strap options a little more tricky. I am lucky enough to have an original "waffle" strap on mine which suits the watch perfectly. I have also used a Marine Master strap on this and that is a great option.

The movement in this one is the 6105b variant of the 6105 movement which is a non handwind but hacking movement. The crown is very unique in that it is a "turn/lock" crown instead of a screw down crown:

When the crown is pushed in all the way the crown can turn just slightly and then it "locks" into place so that it cannot turn anymore. Not as secure as a proper screw down crown but this is a neat solution which Seiko tried out at the time. This watch is watertight though as it was pressure tested by Jack and IWW when the resto was done. I do swim with this one and it did make it down to 30-35 feet a couple of years ago when I dove with it in Mexico. I drive my vintage car and I use my vintage watches. Got to enjoy them!

The caseback on this one is actually fairly boring:

They had a "Suwa" style of back which they used on this model from 1970 until some point in 1974. Then they switched to this style until the watch ended production in 1977. Note: TimothyPatrick has a 1978 6105 but it was made from NOS parts. Speculation is that the 1978 caseback he has was made for parts only and there was no production of a 1978 assembled 6105 diver. Time will tell if this is true or not.

Here are some old pics of it beside a 1974 6105 that is presently at Randall's spa:

See the differences in the casebacks?

Now time to put this watch into context. By that I mean I am going to put it beside some well known Seiko divers so that you can see how the watch stacks up size wise:

Here is the 6105 beside a 6306 diver:

And the SKX007K:

And the Marine Master:

And finally a Blue Monster:

I did not take a current pic beside it with a Sawtooth. Here is an older pre-resto pic of the watch on Marine Master strap beside the Blue Sawtooth:

Is this a worthwhile vintage Seiko diver to own? Absolutely! What you want and what you want to spend are another matter altogether. A nice original example unrestored can cost $400-$450 and up. Factor in a few hundred more for the work. With patience you can find restored examples for $500-$550 or so. The watch will be all done up and "turn key". You will also not have the wait associated with pros like Jack and Randall.

If you are not a stickler for originality you can buy one of these with repro dials and hands for around $300 or so. Be careful of the seller though as they are not all equal. I highly recommend Stephen Go of the Watch Works on e-bay as he is honest about what he is selling and his 6105 repro dials and hands are some of the nicest ones out there.
