【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.

Series 8 is a mechanical watch brand with a modern design that combines functionality and practicality. Introducing the 890 Mechanical, a new model with a sporty look and water resistance of 20 ATM. It is the only model in the current Series 8 lineup that is water resistant to 20 ATM, and features a bi-rotating inner bezel. The original pattern on the dial and tapered metal band give it a sporty look, as well as an urban and luxurious impression.

Time (maximum winding) / / *Accuracy is measured with the movement in a static state. Due to the characteristics of mechanical watches, the daily difference range may be exceeded depending on the conditions of use (time when the watch is worn, posture of the watch, movement of the arm, winding of the mainspring, etc.). The driving time is a guideline. / 20 ATM waterproof / 2 types of magnetic resistance / Luminous (needle + index) / See-through back / Band adjustment: Split pipe type
