Discover this beautiful Seiko 5 SNK809K2 also know as the Military Nylon 21 Jewels. A timepiece for gentleman. Simple, class and practice.
This automatic watch is characterized by a round stainless steel case with black dial, perfectly matching the Nylon strap.
Very present in the Seiko House, the glass of this model is made of Hardlex, a more resistible material than the classic mineral glasses that we find in the entry-level model. The 21 Jewels automatic movement is well known for its reliability and durability.
Note the presence of an opening on the back revealing the mechanism in its entirety… Enjoy

Isabelle –
Watch well received, extremely careful packaging, impeccable watch !!! Just a small downside compared to the delivery time, but apart from that, on top.
DENIS –
Product meets my expectations, fast shipping and neat, all good!
thank you “Conteenium”.
SEBASTIEN –
Product conforms to the description and very good quality !! It is an original.
On the other hand the diameter corresponds well to a wrist “end” (teenager for example)
BG –
Watch ordered in blue version. Received very quickly (in 3 days) with the candy inside that pleased my daughters! Product perfectly in line with your description. I am delighted. Congratulations for your website which offers products with a high quality-price ratio.
This is my second order after a various Seiko and I invite fans of automatic watches at affordable prices to indulge.
Arthur (verified owner) –
Small marvel, with a bracelet brown type flieger .. brilliant
Maxime (verified owner) –
A great watch for every day!
For my part, I added a nato bracelet in brown leather “old school” (more worn than the version cocoa) to bring him a lion of baroudeuse.
For the movement, it is reliable. Watch Forums are right about this.
Sending fast and in addition to candy!
I would recommend this site with eyes closed.
Maxime (verified owner) –
A look and not a lion …
(automatic corrector)
Quentin –
Magnificient ! Can you give us the reference of the bracelet ? Thank you!
RODRIGUES –
Satisfied with the product, beautiful object.
Sending and fast delivery for a DOM TOM order all the more.
Proceed as follows.
Claude –

Je m’intéresse depuis peu aux montres auto, ayant bien fais le tours de ce modèle sur le net je n’est donc aucune surprise bonne ou mauvaise, le modèle me plais, à l’avenir je prendrais surement une 2ème un peu plu chic.
J’aime beaucoup les “Orient”, je vous encourage donc de continuer à les distribuer.
Pour ce qui es de la qualité, j’en jugerai dans quelque années…
Je compte remplacer le bracelet par un modèle “nato” en cuire, dommage que vous n’en ayez par car j’en aurais peu être commander un en même temps.
Je vais déactiver mon compte chez vous, car je n’aime pas accumuler les inscriptions, rassurez-vous, ce ne sera pas par déception.
Bonne continuation,
Eric L. –
I am satisfied with both the watch and your site.
I just regretted not having the manual of the watch ….
Yves M. –
J’ai bien reçu ma montre, je suis très satisfait de sa qualité ,ainsi que de son aspect ,elle me plait énormément .
Qualité de service irréprochable concernant l’information et la livraison du produit, c’est parfait !
Peut être juste un peu plus de choix sur votre site dans les montres hommes dans le style aviateur genre “Archimede modèle Pilot ” mais c’est juste une suggestion personnel
MARC-ELIE –
Hello,
first purchase on Conteenium.com, and I say bravo !! Impeccable service, reactivity correctly calibrated!
Concerning the watch I am also satisfied, although I expected bigger, I must confess that seiko to study the issue well because it is perfect for its use. The next is coming soon!
Chistophe V. –
I am completely satisfied with both the product (seiko 5 miltary) which is really a product that seems of quality, pleasant to sight and wear, and both the quality of service, since I received it in 5 days for a very reasonable price.
Florent A. –
Je suis très satisfait par la montre qui représente selon moi un rapport prix / design imbattable. Elle correspond parfaitement à mes attentes.
Pour être tout à fait transparent, il s’agit de mon premier achat de montre sur internet et j’étais assez réservé tant les mauvaises surprises sont nombreuses pour ce type de produit sur la toile. Ce qui est assez déstabilisant dans votre offre, c’est de voir sur le même site des produits à plusieurs milliers d’euros côtoyer des montres beaucoup plus “abordables” au risque d’attiser la méfiance.
Après quelques recherches sur votre site (mentions légales, siren…) je me suis quand même jeté à l’eau en me disant que dans tous les cas, il ne s’agissait “que” de 99 euros.
Concernant le service client, je ne peux être que satisfait compte tenu de votre réactivité. J’ai particulièrement apprécié le fait d’être informé régulièrement de l’avancement de la réparation.
