■ What is the Presage Classic Series? A dress watch that embodies Japanese aesthetics.

Seiko Presage's ``Classic Series'' is a dress watch line that pursues the inherent beauty of watches. It has a delicate finish and a classic design language, while still retaining the reliability of a Japanese automatic movement. For those who love past models, this series has a strong reputation as ``Why this price?''

This SARX133 is a core shop exclusive model that appears in the classic series in navy color. This is a quiet yet strong piece that combines elegant bar indexes, luminous light, and dual curve sapphire visibility.

■ Navy dial---a color that coexists with depth and calmness.

The biggest feature of SARX133 is its deep navy dial. The choice of navy, which is not as heavy as black or as flashy as blue, is why it naturally blends into a wide range of situations, from business to casual.

Paired with a silver C-ring bracelet, it creates a classic dress watch look. The dual-curve sapphire glass (inner surface non-reflective coating) reduces light reflection, allowing the navy dial to be more clearly seen. Those who know a lot about watches will immediately notice the high quality.

■ 6R55 caliber ─ 72 hours long power reserve

It is equipped with Caliber 6R55. It is a self-winding mechanical movement (with manual winding) that can last approximately 72 hours when fully wound. Calculations that are still working even if you take them off on Friday night and put them back on on Monday morning. This 72-hour number will especially resonate with those who take their watches off on the weekends.

Accuracy is +25 seconds to -15 seconds per day, which is typical of a mechanical device. The elaborate structure of 24 stones can be seen by peeking through the see-through back. The rotation of the rotor, the movement of precisely linked gears—this is the real thrill of mechanical watches. It also has a second hand stop function, allowing you to set the time accurately.

■ Diamond shield x dual curve sapphire ─ Authentic details details

The case has a diamond shield coating. This is a surface treatment that is second only to diamond in hardness, making it highly resistant to scratches and abrasion from everyday use. Along with the dual curved sapphire glass, consideration for long-term use can be felt everywhere.

Case size is approximately 46 x 40 x 13.5mm. The height of 46mm includes the lugs, so the case width is 40.2mm. Weighing approximately 140g, it has the presence of a stainless steel bracelet, but is well-balanced for everyday use. It is waterproof to 10 ATM, so you can wear it with confidence even during sports or around water.

■ Buyer's comment

Presage's classic series always impresses me with how solid they are, but I especially like this navy one. Navy is an exquisite color that is neither too protective nor too playful, making it easy to match with any style. The transparency of the dual curve sapphire becomes clearer when you see it in real life, and the depth of the navy appears even deeper. The 6R55's 72-hour power reserve is also quite convenient, so you don't have to panic at the start of the week. At 132,000 yen, this finish is a good value for money that is typical of Presage.
