HAND POLISHEDAll cases, buckles and bracelets are made in the best solid stainless steel material for watch manufacturing. The fine 316L steel is made in Japan - and all cases are carefully hand polished according to the best craftsmanship standards.
MOVEMENTSMost models are equipped with a movement, that uses a Spron battery. This is a silver oxide battery free of mercury and lead. By applying a high precision anode using a surface process technology and a special material for the cathode, silver and lead are completely removed from the battery. The movement can also use ordinary batteries.
GLASSMost models are equipped with mineral glass that has undergone special hardening procedures to ensure maximum crack resistance. Our ultra-slim Paper series is equipped with highly scratch resistant sapphire crystal.
All 4.8 mm ultra slim watches are fitted with highly scratch-resistant sapphire crystal.
MERCURY AND LEAD-FREE BATTERIESObaku watches come with mercury and lead-free silver oxide SPRON batteries. By applying a highly precise technology the mercury and lead is totally removed from the battery. The movement can also be used with ordinary batteries.
COATINGSAll Obaku watches with colors are coated with a titanium ion plating, which is the most advanced technique for long lasting coatings. It is a mixture of titanium and the desired color, which is merged with the stainless steel base material in a fusion process in a vacuum chamber.
A note on rose-gold plating
Your Obaku watch is made from the highest grade materials available and all platings are of a highly durable mix. Any rose-gold plating contains copper. The nature of copper is that it can oxidize, just like silver can tarnish. Oxidization can happen at different rates depending on humidity and wear and tear. You may be able to polish away oxidized parts, however, due to the nature of copper, it may re-appear, just like you would see on silver jewelry.
STRAPSAll straps are made in genuine leather - and several versions are assembled in multiple layers which gives the straps a rich structure and identity. Mesh and link bracelets are made in the highest quality 316L Stainless surgical steel and offer a comfortable fit on any wrist.
WATER RESISTANCEAll watches are at least 3 ATM water resistant and have been individually tested. Some watches are 5 or 10 ATM water resistant. You can see the water resistance marking on the back case of the watch. Only the 10 ATM watches are suitable for swimming.
GIFT BOXESThe gift box supports the Obaku watch designs by its minimalistic and harmonizing expression, emphasizing the Zen philosophy that less is more.
