**Details of Otsuka Lotec Model 7.5**

The watch features a unique turret design with three windows on the top case, showcasing the jumping hour mechanism for time display. It is equipped with a MIYOTA movement along with a proprietary module that instantly switches the displayed hour, with minutes and seconds indicated in their respective windows.

We minimized the clearance inside the case and the internal module, resulting in a case diameter of 40mm. A combination of hairline and sandblasted finishes gives the exterior an expressive appearance.

**New Specifications (2023 and onwards)**

The model 7.5 has undergone improvements in design, material usage, and processing methods for enhanced operational stability and durability. Changes include upgrading the case material from SUS303 to SUS316L, the glass from mineral to sapphire crystal, and the hour display lens from acrylic to custom sapphire lens. Additionally, the watch sports a buckle engraved with the brand's logo and a specially designed strap.

**Note:** When adjusting the time, always ensure that the crown is turned in the direction to advance the time.

Condition: No scratches or cracks.

Operational Status: Working well.

Included accessories: box, warranty, and booklet.

Dial Color: White

Strap Color: Black
