Crafted in France, our watches are the culmination of a meticulous assembly process carried out by a professional watchmaker. Each component is rigorously selected or manufactured to meet the strict requirements of our specifications. Leave your watch project in the hands of experts! No scratches, dust, or fingerprints under the crystal of your new timepiece!

We cordially invite you to visit our workshop to discover our passion and our commitment to excellence and artisanal craftsmanship.

The regulating organ of all our movements is relubricated and adjusted to guarantee accuracy close to the chronometric standards established by prestigious Swiss watchmaking houses. Each movement is subjected to rigorous testing in six different positions and must adhere to a minimal rate deviation, in accordance with our demanding specifications which stipulate a tolerance of -4/+5 seconds per day. This differs significantly from the default standards of Seiko automatic movements which can show a variation ranging from 30 to 90 seconds when leaving the factory.

All the gaskets of your watch - crown, bezel, case back, crystals - are fully lubricated to ensure water resistance in accordance with the required specifications of the case, ranging from 100 to 300 meters depending on the model you choose.

We then carry out rigorous compression and decompression tests to validate this water resistance. The results of these tests, certified by our state-of-the-art equipment, are included in the complete package of your watch, thus assuring you of quality and reliability.

Unlike most amateur modders who offer the same services as us, we have a large portion of our parts manufactured, such as bracelets, cases, and hands, according to our specifications, to ensure quality control and machining tolerances for the parts that make up our timepieces.

No ALIEXPRESS or Wish parts inside our watches!

The N.A TIMEKEEPING experience would not be complete without its famous full set. A genuine box accompanies your new watch. This box is not just a container; with this case and the accessories that make up the full set, your watch benefits from a setting that matches its refinement, making your acquisition a true pleasure from the very first glance.

No ghost workshops or promises of so-called "made in France"! (Oh yes, you know who I'm talking about, all you pro-Seiko people and so on!)

Our workshop is a storefront shop open to the public in the heart of Paris where all the timepieces offered by our workshop are manufactured.

When you enter our workshop, you see our watchmakers, in their lab coats, busy at work!

You can change every part of our existing models - hands, dial, bezel insert, anti-reflective coating on the sapphire crystal and much more! To do so, please let us know when placing your order!

We offer the possibility of further personalizing your timepiece by providing an engraving service, as well as the option to customize the dial inscriptions for a unique result, reflecting its future owner.

Confident in the quality of the assembly we offer and the components that make up our creations, the N.A TIMEKEEPING workshop guarantees all timepieces for three years. In the event of malfunction or excessive chronometric deviation, the necessary steps will be taken very quickly, as after-sales service is one of our priorities.

We also offer a free complete overhaul of the movement at the end of these three years to ensure that it is in good condition to face the years not covered by the warranty. The return and shipping costs are covered by our workshop.

The automatic movements we use to equip our timepieces are certified MADE IN JAPAN. Indeed, most of the movements in the NH series (34/35/36 etc.) are often manufactured in CHINA/MALAYSIA (not to mention the counterfeits sold on Chinese marketplaces like Aliexpress), by SEIKO subcontractors, with a quality that does not meet our specifications.

You will find in your box a certificate of authenticity for the JAPANESE origin of the movement, as well as its chronometric report printed on paper for the different positions. And also the original ROTOR with the word JAPAN on it (rotors from other origins do not have it).

Optionally, you can discover the ultimate decoration of our movement, which features a mainplate adorned with peripheral pearling and Geneva stripes (TK-1). The retaining screws are hand-blued for a finish worthy of the greatest manufactures. This movement will be visible through a sapphire crystal on the caseback. For true lovers of fine watchmaking!
