I am selling this item because it was different from what I imagined when I purchased it. It is in beautiful condition, having only been tried on indoors. There are some scratches near the belt buckle due to the buckle's interference, but they are not visible when worn, so there should be no problem. Below is the product information. ■size/spec■ Diameter: 39mm (Thickness 12.9mm) Belt width: 2cm 【Body】 Stainless steel (316L stainless steel) 【Belt】 Stainless steel 3-link metal band 【Movement】 Seiko Cal. NH35 automatic movement (Made in Japan) Automatic winding (with manual winding mechanism) / Average daily rate +45 seconds to -35 seconds (at 5°C to 35°C) Operating time: Approximately 41 hours when fully wound Naval Watch Produced By LOWERCASE Based on vintage watches, the case shape, acrylic lens (with cyclops), metal band, and hands are all original designs, with attention to detail to create a modern and vintage feel. The case, case back, and metal band material are made of 316L stainless steel. The windshield is made of acrylic to give it an antique feel. A cyclops (fish-eye) is attached to the date part to ensure visibility. The watch 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 to further pursue a vintage feel. The luminous paint on this model is slightly inferior in terms of luminous time and light compared to other models, as the emphasis was on the atmosphere. It is water-resistant to 5 atmospheres, so it can be used for daily water work and tasks.
