The 6309-7040 is undoubtedly one of Seiko’s most iconic divers. Manufactured by the brand from 1976 to 1988, the 6309 was the bedrock of Seiko’s recreational diver collection for approximately 12 years. Amongst Seiko fanatics, it remains one of the firm’s most popular pieces. So when Seiko first announced the SRP77x, the brand’s reissue of.

Seiko provided the 'approximate'dates of production for the difference movement calibers, but said theyare unable to give info about individual models as they don'thave detailed records.

Updated stylesheet to make fonts larger and text more legible. Content remains the same as the original. Models:. 6217-8000.
6217-8001. also referred to as '62MAS' or by dial number - 6217-8000T.Details:The 6217 is Seiko's 1st diver. It's often referred to as '62MAS' (the 62 stands for the 62 seriescaliber movement used in the diver). It's rated to 150m.(For a good intro to the historyof Seiko's development of the professional divers, see Ryan's post from the Seiko &Citizen Forum.)The cal.
6217A automatic movement is 17J and runs at 18,000 bph. It has a date-only display and was used also in the World Time models.6217A is a cousin of the 35J 6218A movement, which has an added day wheel and was used in the Seikomatic and Weekdater modelsof the late 60's.Pics:. Shawn's Diver Heaven:.More info:. Details:Seiko made 2 series of 6105 divers: 6105-8000 and 6015-8009 are earlier models, whilethe 6105-8110 and 6105-8119 come later. All models are rated to 150m.The cal.
6105 movement comes in 2 variations - 6105A and 6105B. They are both 17J and run at 21,600 bph.They have a quickset date-only calendar mechanism.From, it seems that are 6105 movements that hack and there are some that do not.In a S&C Forum post, ' says, 'The first series 6105 does not hack. The dial is signed 'waterproof'. The type that hacks will have 'water resistant' on the dial.' But Mike/'mmounce' says, 'I have 3 that all hack. One of them is an early model with water 'proof' instead of 'resist' on the dial and caseback and it hacks also.' So it's unclear which specific models of the 6105 divers hack and which do not, though both exist.The 6105-8000 and 6105-8009 models use the cal.
6105A movement and have symmetrical cushion cases.The 6105-8110 and 6105-8119 models come later and use the cal. 6105B movement and have larger asymmetical cushion cases.The 6105 divers use the mechanism (and not a screw-down crown).Here's a detailed description of the different models by ':The 8000 and 8009 are the same watch. Seiko just assigns a 0 or a 9 as the last digit depending upon the country that the watch was exported to. I'm not sure where the 0's vs. The 9's were destined for though. So anyway, the same goes for the 8110 and 8119.
The 800X series preceded the 811X series.There are differences between the 8000(9) and the 8110(9).First of all there's the bezel. It's bi-directional without clicks on the 800X series. The 811X's are unidirectional with clicks. Correction: The 811X should be 'bi-directional with clicks.'
According to,'The smaller cased 8000,8009 do not have a click ball,just friction o-ring for tension.The large case 8110,8119 have the click ball.' The 811X's are also much larger at around 45mm vs 41mm. Some like the slightly asymetrical case design of the 811X's while others like the more conservative 800X's.Neither of the two watches can be manually wound, but some (maybe all) of the 811X's actually hack. One really nice feature that you get with the 800X's is a signed crown. A real rarity with Seiko both vintage or contemporary.Ever since Seiko started putting out its line ofhardcore diver's watches, folks have been usingthem for all sorts of extreme situations.Here's anabout what he and his 6105 went through:My trusty 1966 6105 Diver has withstood one Alaskan plane crash (smallplane) after being left in the woods 'lost' for 6 months after itbroke from my wrist and flew out on crash impact until we could comeback and salvage the aircraft in the spring. (Lived in Alaska 24years) Another was our helicopter went down in the North Atlantic inthe late 70's during a storm and a trip to the offshore oil platforms,we were in a raft for 7 hours in heavy seas and freezing spray.
Arefinery explosion in France in the 80's when several people close bywere killed and my Seiko once again became airborne and was foundseveral hundred feet away. I just had in restored by Eric in Seattleof EMW and it's looks like a new watch. Any way I guess that'stough.The 6105s and the 6309s that follow them were.According to a S&C Forum contributor, the 6105 divers were issued to one of the.In the 1979 Francis Ford Coppola film 'Apocalypse Now,' Captain Willard (played by Martin Sheen) was an Airborne Army Ranger who wore a diver.There's a closeup video capture shot of the watch (pic by ).The 6105 supposedly also appeared in the 'The Deep.' According to 'The character 'Romer Treece'wore 2 Seikos actually, one was a VERY old 60's 150m dive model (non-locking crown) and the other was certainly the 6105-8XXX(of Apocalypse Now fame) in a brief underwater shot.'

Models:. 6306-7000. 6306-7001Details:The cousin of the 6309, the 6306 is a 150m diver that looks andfeels identical to the cushion-cased 6309, but was marketed only in Japanand uses the cal.
6306 movement.The cal. 6306 movement has 21J and runs at 21,600 bph. It hacks and has a quickset day/datecalendar mechanism with a Japanese/English day wheel.The 6306 divers are much rarer to find than the 6309s because their productionyears were relatively short and they were Japan-only models that usea 21J hackable movement (compared to the 17J non-hacking movements in the 6309s).Like the 6309, the 6306 diver has a bi-directional non-locking bezel.According to, the designer of many of Seiko's diver watches, the 6306 diver was put into production slightly beforeits brother the 6309. The 6306 diver differs from the 6309 in that the cal. 6306 movement has 21J (as supposed to its base caliber 6309's 17J)and it has a Japanese/English day wheel. A promotional pic of the 6306 diver from an early Seiko catalog is. Also see description of the 6309 below.Pics:.Shawn's Diver Heaven:.More info:.

6309-729B? (very rare model, with slimmed-down case and orange dial)Details:The 6309 divers replaced the 6105 as the standard models of 150m divers.The 6309s were marketed outside of Japan while a version using the 6306 movementwas sold only in Japan (but for a relatively short 5 years).The cal. 6309 movement is of the 6105.It has 17J and runs at 21,600 bph. It's non-hacking and has a quickset day/date calendar mechanism.Like the 6105, there are 2 series of.The earlier versions - 6309-7040 and 6309-7049 - are housed in big cushion cases andhave round markers. The later versions - 6309-7290 and 6309-729A/729B - have slimmed-down cases and rectangular markers(which make them very similar to the current SKX007/173 models). While the earlier 6105 divers used the 'turn and lock' crowns,the 6309 crowns are all screw-down. The 6309 divers seem to all have bi-directional non-locking bezels.Some people have asked how the 6309-7049 and 6309-7040 differ.The consensus among S&C Forum collectors is that there's no differencebetween the 6309-7040 and 6309-7049 models.

Tokunaga, the designer of many of Seiko's diver watches, has provided some valuable historical info about the 6309/6306 divers.The 6309 and its brother the 6306 were both put into production in 1976 - the cal. 6309 movement was designed first (and serves as the basecaliber for the 63 series of movements), but the 6306 diver was put into production 'slightly first,' before the 6309.He also included a scan of theas well as promotional pics of the and watches from early Seiko catalogs.For a comparison of the details of the 6309-7040 and 6309-729A with lots of pics, check out.There are many anecdotes of folks who have put their 6309s to the torture test.writes:I've come out of lurking mode to present my version of anextreme torture test on the 6309-7049 150mm diver.

7002-7009. 7002-700A (blue and red bezel). 7002-700J (Japan-only version, with '17 Jewels' on dial, blue and red bezel). 7002-7020 (200m model with a steel Tag-like bezel design similar to the current SKX171 model). 7002-7039 (200m model, in black as well as blue-and-red bezels)Details:The cal. 7002 movement has 17J and runs at 21,600 bph. It's non-hackingand has a quickset date-only calendar mechanism.By the late 1980s, Seiko has changed the case design of the diversfrom the earlier large cushion shape to a slimmed-down case likewe see today in the SKX007/173s.When the 7002 divers replaced the 6309s,they inherited the small case design from the 6309-7290.The 7002s all have rectangular markers.There are several different variations of the 7002 divers:.
The 7002-7000 and 7002-7009 seem to be identical, with the difference being only themarketing regional code at the end of the case number (0 and 9). These 2 are both150m divers. Their inscription says 'WATER 150m RESIST' on the dial. The 7002-7001 is almost identical to the 2 above but the dial has the line '17 Jewels'added underneath 'WATER 150m RESIST.' . The 7002-700A is a 150m diver with a blue-and-red bezel. The 7002-700J, according to Shawn Taylor/shawn,is another variant - 'Japan only market version with '17 jewels' on dial, but with red/blue bezel.'
. The 7002-7039 seems to be the first 'low-end' diver modelthat got its water resistance rating promoted to 200m.
While the 150m 7002 divershave bi-directional bezels with 60 clicks (the traditional design),the new 200m 7002-7039 has a uni-directional locking bezel with 120 clicks.The dial says 'DIVER'S 200m.' The new features introduced in this diver(200m water resistance, uni-directional bezel with 120 clicks as well as thedial inscription) will carry on in the 7S26 models that succeed the 7002.Pics:.Shawn's Diver Heaven:.More info:.
