This watch is as slim as two-coins and still gets to pack twelve Swarovski crystals on its dial. Notat Steel is part of the worldÕs slimmest watches in its price category club. No more than 4.8 mm to be exact. Numbers can talk, but this one needs to be worn before you know what we mean. We prefer Obaku wearers to have peace of mind when it comes to their watch. ThatÕs why the entire Notat series sports sapphire crystal for increased protection and a scratch-proof experience. We didnÕt skimp on the price either and are proud to say that we consider all aspects of our watches.
