Vintage Watch Seiko 6105

The Seiko 6105-8110 is a cult model among the Seiko diver watches

Every story has its beginning, and for some reason one suddenly becomes interested in a particular watch brand. In this article, originally in English have to have Seiko. Therefore, this article is dedicated to the Seiko 6105, more precisely: the Seiko 6105-8110.

The 6105-8110 aroused my interest in the vintage watches of Seiko. I can’t remember exactly how I came across it, but I know I discovered it on ebay four or five years ago, but I didn’t keep it busy. At the time I did not know enough about Seiko and saw no reason to spend a lot of money on a Allerweltsmarke, as I thought. But somehow the clock met me again and again in forums, and so I decided to read something in the topic. With the result that I wanted to have a Seiko 6105-8110 in my collection. So I started looking for a suitable specimen. After a few months I found one in the watch SCWF (a forum for Seiko and Citizen watches) at a trader from the Philippines (yes, even there are good dealers) and bought it. It took his time–at least a month–until the clock had passed the German customs and finally lay ahead of me. But the anticipation was worth it.

Style Making: The enclosure of the vintage watch Seiko 6105

The 6105er series replaced 1968 the first professional dive watch from Seiko, the 62MAS, and was produced until 1977. In the first version, it had a clear symmetrical housing. After a few years it was replaced by the asymmetric version, which can be seen on my pictures. The special thing about this design is that it is the first step in the direction of the large, disc-like enclosure that was later used in the popular 6306er and 6309er series. It was also the first asymmetric housing of Seiko with the integrated Crown protection, which is still found today in the SKX007 models.

The Seiko 6105 is in diameter impressive 44 millimeters in size and features an automatic work with 17 stones, your balance completed 21,600 half vibrations per hour. The Crown offers a quick adjustment of the date, but the work cannot be drawn by hand. According to the dealer, the watch is waterproof, up to a depth of 150 meters (equivalent to 15 bar). It also has a rotating and resting bezel on both sides. As glass, which makes the scratches clear, the Seiko Hardlex mineral glass was used. The belt push width is 19 millimeters. The crown is not screwed, but is sealed with a rotating system that is unique to this model; However, the functionality and longevity was controversial compared to the traditional screw crowns. The housing base is typically screwed.

Still impressive: The dial of the Seiko 6105-8110

The processing of the Seiko 6105 is impressive. The upper side of the housing has a mat, the flanks are polished. But the case as a whole is really fascinating: from almost every angle it speaks to the viewer, offers new insights and acts almost organically. The influence of the 1970s is unmistakable (in the positive sense). The dial is functionally designed, the hour markers carry luminous mass. The scale for the Minutes frames the indexes and is taken from a bezel that tends towards the glass. This bezel, which was also used in the first version of the 6105, is still present in the diving watches of Seiko. The rectangular pointers are very simple and are designed with luminous mass. It is interesting, however, at the second hand: the otherwise simple pointer ends in a unique shape, which encloses an originally red-colored point and a point of luminous mass, the luminous mass in turn fits to the rest of the dial. The pointer extension is a symbol of the model, which still jumps into the eye if the red is faded to the point of recognition. One last note to the dial: the label is reserved, it includes the brand logo of Seiko in the form of a chrome applique, the inscription “Automatic”, the indication of the waterproofness and below the Suwa symbol. So the design follows the motto “Less is more”, the Seiko 6105-8110 is simpler than its predecessor 62MAS. The classic Seiko bezel, which was also used in the 62MAS, now shows an orientation triangle at the 60. Even today nothing has changed, the bezel still stands out because of its simplicity.

The Seiko 6105 has been widely known since her appearance in “Apocalypse Now” on the wrist of Martin Sheen as captain Willard. The famous image can easily be found in a short online search. The 6105 was quite popular during the Vietnam War among U.S. soldiers. It was offered in retail outlets for members of the US Army, and although it was not cheap, it was still cheaper than, for example, the Rolex submariner.

Indispensable for the vintage watch: The rubber band with waffle pattern

Because of their diameter of 44 millimeters, it would be expected that the Seiko 6105 is like a heavy monster on the wrist, but that is not the case. Perhaps it is due to its gentle forms or the narrow width of the webs, at least the watch feels more like a diameter of 40 millimeters. Speaking of narrow band impetus: The bracelet is not an ordinary rubber band, but a band with a waffle pattern, which was standard for watches like this one. In my opinion, it is the only true bracelet for you. Of course it is not easy to find original tapes because they are very rare, expensive and often also damaged. Fortunately, the ebay merchant “Wjean” offers excellent refinements that fulfill its purpose absolutely. If you get a 6105, I strongly recommend that you get one of these tapes.

What to consider when buying a vintage watch Seiko 6105 is valid

Finding a Seiko 6105 is not particularly difficult. However, if you are looking for a good specimen, it becomes more complicated. At my watch, you may have seen that the dial shows “Wabi”, i.e. the decomposition of the luminous mass typical for Seiko vintage watches. Compared to many clocks, the example is not bad, and compared with the vast majority of the reworked watches it looks authentic. This leads me to an important point: several copies of the 6105er series are available on the market, and most of them have been changed. These changes range from reworked pointers and dials to completely exchanged parts. The second hand provides an important clue: if the colors are too intense–especially when compared to the rest of the dial and the other pointers–then something is wrong. When buying a 6105 you have to be very careful and assure yourself that you get something that also meets the expectations. In general, I think that flawless models are very rare, since most of the watches have already been a lot of fun. However, there is, of course, at a corresponding price. Well-preserved specimens have now exceeded the 1,000 dollar mark, and for excellently received, you have to reckon with 1,500 dollars and more. Currently, restored and well-revised specimens seem to be in demand, but I am an absolute proponent of the original condition. Another element to consider is the crown. Make sure that it has the original “lock” and the corresponding arrow for the direction of rotation. Also the Lünetteneinlagen are often exchanged. You should also pay attention to this.

The Seiko 6105-8110 remains the favorite among the vintage watches

The Seiko 6105-8110 is a cult among Seiko’s dive watches. It has a great housing shape with an equally attractive dial design. This watch gave me the rash to collect most of the dive watches from Seiko. And you–perhaps the most distinctive model of all–is still one of my favorites. The fact that she was seen in a cult doesn’t bother me any further. Which Seiko diving are you fascinated by?
