1974 NOS Seiko 6117-6410 Navigator Timer Review




Ok firstly this review is dedicated to the excellent and extremely courteous Isthmus who kindly asked if I'd do a mini review.Well its a NOS Seiko 6117-6410 Navigator Timer dating from May 1974 and purchased from a Jeweler who had it sitting on a shelf for an amazing 30 years!!!!!

The sales tag states price as $205 Hong Kong dollars[img]![/font]
[font=arial]The bracelet appears original and just about fit My 7.5 in.wrist but its a tight squeeze.[/font]

Diameter of watch is 40mm and lug width is 20mm so i put the watch on an aftermarket 20mm rubber strap.[/font]

The caseback has,"Seiko",plus serial number and movement number on it plus words,"Water Resistant",i believe these were only good to 70 Meters but i will not be checking out the watch's water resistant qualities any time soon in fact there are some version that have the words,70M Water Resistant", actually on the dial but there are later versions like Mine with this term removed.Finally We have a small,"Suwa", symbol indicating what factory in Japan watch was assembled in i trust this is what it symbolizes but I'm happy to be corrected. . . . Also the Red/Blue colour scheme on the dial signifies day and night another good quick check in case You're wondering whether You are disturbing someone's sleep when calling them from abroad![/font]

The crown is recessed into the case and is non-screw in it serves 3 functions:

[/font][font=arial]1. In the fully in position it turns the GMT bezel so that You can align it with a second Timezone/City/Location it turns quite easily i've got it set to NYC time i also found out that this Watch was quite popular with Pilots/Flight Engineers.[/font]
[font=arial]
2. Pull the Crown out to first click and it sets the date.[/font]
[font=arial]
3. Pull crown out to second click and it stops the second hand and allows You to adjust the hour/minute hands therefore the movement is hackable and is 17 Jewels - so far time keeping is running fast but not more than a minute.[/font]

The casing looks totally untouched and tampered with if its aftermarket its damn near perfect![/font]

[font=arial]The crystal rises about a couple of inches from the rest of casing and feels exactly the same as the material used by the Omega SpeedMasters (ie, Acrylic/Plastic-type material). Again I would hope Seiko experts would kindly chime in about its material/properties.

[/font] [url=http://www.thewatchsite.com/index.php?action=dlattach;topic=114.0;attach=31821;image][img][/url]

[font=arial]Again Crystal appears totally unmarked no chips/scratches on it.[/font]

[font=arial]The hands/markers are all original because there are very minor signs of aging consistent with a watch over 30-years old and there is lume but very,very minimal i have made a decision not to have hands/markers relumed as i prefer to keep it as it is a testament to the originality and history of the watch.[/font]

[font=arial]
Simply put this watch has not left My wrist the two days i've had it and My only complaint is that the GMT bezel is very easy to move thus Your second timezone alignment can be easily moved and also that aftermarket parts for this rarity will probably be scarce.[/font]

[font=arial]So there is it Seiko 6117-6410 Navigator Timer i kindly request Seiko experts/fellow forum members chime in with any further insights/tidbits. Thank you for letting Me share [/font]

You're right, parts are tough to source. Be careful with the stem, some sellers out there will advertise as having them for this movement but they lack the feature to rotate the inner bezel. I have the older 6117 6019 world timer. If you have yours serviced and adjusted I'm sure it can be much more accurate than a minute. When I got mine it was in a jar of broken watch parts. The crystal was so bad I could barely read the dial, but by the time I had it out of the jar it was ticking away. over they course of the next 3 days I checked it against an atomic clock and it was only a few seconds off. the 6117 is an AMAZING movement. In regards to movement parts if you ever need them many parts of the entire 6xxx line are shared.

From the review above, it is said that the movement is hack.

I have 2 caliber 6117
World time 6400 ca 1973 and navigator timer 6410 ca 1974, both is non hacking

Please anyone explain if there is two kind of movement,

Thanks and regards,

Joy
