Absolutely brilliant watch.
I am very impressed.

Une très belle tool watch

Expédition un peu longue vers la France ; j'ai beaucoup apprécié le prix annoncé taxe d'import comprises.
Très belle montre NMK11 BB59, juste la perle réfléchissante du triangle rouge de la couronne n’est pas très réussie : forme trop volumineuse par rapport au triangle rouge, le cerclage du point luminova est minimaliste, sa luminescence est faiblarde et pas à la hauteur de la luminescence des index mais l’effet passe quand même. L’action de la lunette est cool, plus facile que celui de mes autres Seiko! Très bel ensemble.
Le mouvement NH36, à gardé ses disques de date et jour ce qui provoque une position fantôme de la couronne. Il est assez bien réglé : trop de beat error (0,9) mais exact (4sec/d)
Le bracelet cuir d’origine est de bonne facture, avec des pompes rapides ce qui est agréable mais il est trop épais (3,2mm) pour permettre une boucle classique double plis avec sécurité (ép.2,8mm max) que j’utilise toujours . Je l’ai remplacé par un bracelet cuir Motown Teck de chez SELECT-HEURE en cuir qui respecte le coté chaud du décor de cette montre.
Une belle tool watch dont j’ai déjà eu des compliments.

NMK11 a fantastic build and great homage

The Namokimods website has a great selection of pre-built watches, kits along with a great selection of components to customise your watch. The online order process is slick, I chose pre-built and the piece has a flawless fit/finish. The hands, indices and bezel are all nicely coordinated and look like quality components. The bezel action is crisp and all components line up perfectly. The overall design is very close to the BB58 but at a much lower price point! The movement keeps good time and doesn't need winding/wearing as often as my other pieces. The lume is very impressive. The leather strap initially feels stiff but doesn't affect wearing the piece, hopefully it will soften over time. Overall, I would highly recommend Namokimods and I'm already looking at my next purchase..


A fantastic build and homage, I luv the clean design, all the details work so well together 👌 The watch keeps good time and the ability to swap out parts from the Namokimods website is cool 😎 The lume is very impressive and lasts for hours. The strap is comfortable albeit a bit stiff initially but seems to be bedding in with use. The Namokimods team are very helpful and provide engaging emails. Highly recommended 👌
