◆ From SEIKO, a top global brand, comes the automatic (self-winding) model of the "Seiko 5 (Five) Collection Series," a crystallization of precision technology crafted by skilled artisans with years of experience. ◆ This is a rare, fully "MADE IN JAPAN" model. There are "JAPAN" engravings on the buckle, case back, and at the 6 o'clock position on the dial. While standard models often have Japanese-made movements or parts assembled outside Japan, like in Southeast Asia, this model is manufactured entirely within Japan by SEIKO, making it a high-quality watch. ◆ The bezel has a gleaming polished finish combined with satin, and the strap is a matte hairline stainless steel belt. The clasp is a one-push tri-fold buckle that can be easily operated with one hand. ◆ With a see-through back (skeleton back), you can visually enjoy the movement of the mechanical watch's rotor and balance wheel. ◆ In terms of specs, it features LumiBrite luminescence, a day-date calendar, and everyday water resistance, offering sufficient functionality for daily use. The day-date calendar is particularly convenient, with the ability to switch between English and Arabic day notations. ■ Movement: SEIKO Automatic Movement (Cal: 7S26) ■ Case: Stainless Steel, Strap: Stainless Steel ■ Crystal: Mineral Crystal ■ Day-Date Calendar (English & Arabic) ■ See-Through Screw Back ■ LumiBrite Luminescent Coating ■ Water Resistance for Daily Life ■ Size: (Width) approximately 43mm, (Length) approximately 52mm, (Thickness) approximately 11mm ■ Weight: approximately 143g ■ Wrist Circumference: approximately 15-20cm ■ Accessories: SEIKO BOX, warranty, etc. ※ The URL for the English manual for this model's caliber (7S26) is as follows: https://www.seikowatches.com/jpja/-/media/Files/Common/Seiko/instructions/Japanese/7/7S26/7S26.pdf We will inform you via message if there are any changes to the URL, so please rest assured.
