Just a reminder for this special 1st gen. 6105 8110 Seiko diver. Your offers are welcome.

:

: Up for sale is this rare SEIKO 6105 8110 Proof/Proof diver
: watch. At first glance it may look like an ordinary 6105 with
: different text on the dial. But once you have one in your hands
: you can clearly see more subtle design differences.
: Beside that, the Seiko 6105 is a real iconic diver watch in the
: SEIKO history. The 6105 has earned a legendary status among
: collectors due to it's groundbreaking asymmetric case design,
: quality that rivaled Rolex and Omega dive watches, and it's
: provenance as the go-to watch for those who served in the
: jungles of Vietnam in the late 60's, early 1970's.

: The watch for sale is a 1st gen. prototype of the first series from
: mid 1970, which was only produced for a very short period of 3
: months (May, June, July). Then SEIKO removed the
: "Proof" text and started using "Resist"
: leaving these early examples to be quite rare and special. But
: it's not only about the text. The watch shows some more
: essential differences to the later manufactured watches, so that
: these early examples are quite rare and special. For all those
: interested, please take the time to read the detailed
: description below, which documents the specialty of those early
: SEIKO 6105 8110 divers.

: The watch is 100% original SEIKO. Everything works as it
: should. It runs great and was overhauled by a watchmaker last
: year. The second hand has been replaced with an original old
: one.
: The bezel rotates well and engages perfectly. The crown locks
: perfect. The date switches cleanly and the movement runs good,
: keeping the time properly.
: Overall, the watch is in excellent used condition, showing the
: normal signs of age and wear of a 50-year-old watch.

: So, what this means is you have the opportunity to acquire a very
: rare specimen indeed. And this one is quite nice. Original Dial
: and hands (second hand has been replaced with a original Seiko
: second hand), original lume. Original thin case. The Proof case
: is much thinner from top to bottom - it is very noticeable. Also
: the crown area is much more curved and thin - very elegant crown
: guard lines where the Resist simply looks blocky by comparison.
: The lugs of the Proof are also more tapered and streamlined. The
: 6105-8110 Proof definitely has a much more streamlined and
: elegant look. Original Crown with Locking pin working as it
: should. Original 6105B movement with Hacking with early
: chamfered edges Original Movement was cleaned and serviced and
: is keeping excellent time

: Reflecting the rarity, price is set to 3250 Euro. Recently a
: ebay listing for such a watch ended with a price of 5200 USD.

: We all know that prices on these fantastic vintage Seiko's have
: gone up a lot in the past years. This is a nice opportunity to
: own one.
: Thanks for looking. Kind regards, Alex

: The watches of the first 6105-8110 batch production series (from
: may, june, july 1970) differ in the dial, case, caseback and
: crown. Both the dial and the caseback show the words
: "Proof" instead of "Resist" they used later.
: The case is also thinner than the "Resist" version.
: The crown is also designed differently. These features can only
: be found on the early examples of the Seiko 6105 8110 range.
: The differences in detail:

: Dial: text “WATER 150m PROOF”, also matt, non-polished
: indices. The dial code is: JAPAN 6105 8000T

: Case: In short, the later „resist“ cases are thicker and
: clunkier. The proof case is noticeably thinner and therefore
: looks more elegant.
: The Seiko 6105-8110 was the first Seiko diving watch with the
: characteristic asymmetrical case shape. This makes it very
: comfortable to wear, also because it is so thin - the proof case
: is even thinner. In addition, the crown area is much more
: rounded and thinner. You can see that especially in the very
: elegant crown protection lines, which in comparison with the
: resist case looks simply blockier. With the „resist“ cases
: used later, the lines of the crown recess are much straighter.
: The lugs of the proof case are also tapered and more
: streamlined. The fall lines are noticeably thinner and more
: streamlined compared to the resist case. The lugs on later
: resist cases are much thicker and blockier, I would call them
: "shoulder-shaped". If you have watches with both case
: shapes at hand and you compare them with one another, the
: differences are very noticeable. The 6105-8110 Proof / Proof
: definitely looks a lot slimmer and more elegant.

: Back cover: The so-called “Horseshoe” inscription with
: 6105 8110, “Water Proof”, serial number from May, June or
: July 1970.

: Crown: 6 grooves for each of the 6 sections. Later, the
: crown was changed and made with 7 grooves, and over the years
: they changed it again to 8 grooves.

: Movement: Early version of the 6105 movement with bevelled
: edges. With second stop, of course.

: Hands: Mainly the Proof/Proof unse a long second hand. In
: this watch the second hand was replaced with a original Seiko
: 6105 second hand.

: My watch for sale is unpolished and of course has age-typical signs
: of wear on the case, bezel, but nothing dramatic. The case back
: shows signs of opening. Look at the photos. In real life, the
: watch looks much better than on these macro photos!
: I tried to capture the state as well as possible. Please look
: carefully at the pictures. For the pictures, I only took the
: watch out of the storage box and photographed it with my
: smartphone. So it's not for aesthetes, but honestly anyway.
: Nothing has been specially polished, so you may also see dust
: particles and streaks from touching or reflections from
: lightning.
