Case and Crystal

The case and crystal of the watch are crucial components that determine its overall appearance and durability. In the case of the Case and Crystal timepiece, the shape and design are expertly crafted to create a sleek and elegant aesthetic. The case is made of high-quality stainless steel, offering both durability and resistance to wear and tear.

The crystal, which is the transparent cover protecting the watch face, is made of scratch-resistant sapphire. This ensures that the watch remains free from unsightly scratches, allowing for a crystal-clear view of the dial at all times.

To further enhance the aesthetics, the Case and Crystal watch features unique and beautifully designed hour markers. These markers not only serve the practical purpose of indicating the time accurately, but they also add a touch of sophistication to the overall design. In addition, the logo of the brand is expertly displayed on the dial, symbolizing the quality and craftsmanship of the watch.

The stainless steel case is free from any visible scratches or dents, while the sapphire crystal remains unblemished. This attention to detail ensures that the watch retains its original allure and remains visually appealing for years to come.

Crown and Medallion

The crown and medallion of a watch are often overlooked, but they play a significant role in both functionality and aesthetics. In the case of the Case and Crystal watch, it features the original King Seiko crown, adding a touch of authenticity to the timepiece.

The medallion, located on the crown, showcases the brand’s insignia, further emphasizing the attention to detail that has been invested in the design of this watch. The medallion is in pristine condition, with no signs of wear or damage, ensuring that the watch retains its elegance.

Case Edges and Bezel

This attention to detail demonstrates the meticulous craftsmanship that has gone into creating this watch.

The lugs of the watch measure 18mm, providing a comfortable fit on the wrist. This ensures that the watch not only looks stylish but also feels comfortable to wear throughout the day.

The Case and Crystal watch features a solid case back, enhancing its water resistance capabilities. The waterproofing of this timepiece ensures that it can withstand various water-related activities, such as swimming or showering, without compromising its performance.

The case back of the watch is secured with screws, adding an extra layer of protection. This screw back design ensures that the case back remains securely in place, preventing any water from seeping into the watch and damaging its internal components.

The buckle of the Case and Crystal watch is an aftermarket addition, providing a secure and convenient fastening mechanism. The buckle is designed to complement the overall aesthetics of the watch, adding to its visual appeal.

The functionality of the day-date feature in the Case and Crystal watch has been thoroughly checked to ensure proper operation. The day-date complication allows you to conveniently view both the current day and date at a glance, offering practicality and ease of use.

The hacking motion of the watch is another noteworthy feature. The hacking function allows you to stop the seconds hand, enabling precise time-setting. This feature ensures that the watch can be synchronized accurately with other timekeeping devices.
