【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

This product is assembled and manufactured in Japan. (Made in Japan) Body: Stainless steel (316L stainless steel material) Belt: Stainless steel triple metal band 20mm~18mm tapered Movement: Seiko Cal.NH35 automatic movement (made in Japan) Automatic winding (with manual winding mechanism) / Average daily difference +45 seconds to -35 seconds (at 5 Degree C to 35 Degree C) Operating time Lasts approximately 41 hours when fully wound Comes in a dedicated paper box Based on a vintage watch, the case shape, acrylic lens (with Cyclops), metal band, and hands are all original designs. We created it with attention to detail, giving it a modern and vintage feel. The case, case back, and metal band are made of 316L stainless steel. The windshield is made of acrylic to give it an antique feel. A cyclops (fisheye) is attached to the date section to ensure visibility. It uses a Japanese automatic self-winding movement, making it a product that can withstand modern use in terms of functionality. The luminous paint on the numbers, indexes, and hands on the dial uses "LumiNova (R)" paint, which is only allowed to be used on Swiss watches, and is colored ivory in pursuit of a vintage feel. The luminescence of this model focuses on the atmosphere, so the luminescence time and luminosity of this model is somewhat inferior to that of other luminous models. The water resistance is 5 ATM, so it can be used for daily water work and work.
