Seiko - Unknown - Sans prix de réserve - 7B42-0AT0 - Homme - 2000-2010

Introduction

Offered here is a SEIKO Radio Wave Control Solar men's wristwatch, reference 7B42-0AT0.

This model features a refined black dial with applied silver-tone hour markers, a three-hand analog display, and a practical date window at 3 o'clock. The stainless-steel case is paired with a black leather strap, giving the watch a versatile appearance suitable for business, formal, and everyday wear.

Powered by Seiko's radio-controlled solar technology, the watch combines light-powered operation with automatic time correction when a compatible radio signal is successfully received.


Historical & Collector Value

SEIKO has a long history of developing quartz, solar, and radio-controlled watches, with a strong emphasis on accuracy, reliability, and practical everyday use.

The 7B42 caliber represents Seiko's integration of solar charging and radio-controlled timekeeping. The movement stores energy generated from light and is designed to synchronize the time through compatible standard radio signals when reception conditions permit.

This 7B42-0AT0 is an appealing example for collectors and users who appreciate Seiko's technologically advanced watches while retaining the appearance of a traditional analog dress watch. The black dial, stainless-steel construction, leather strap, and relatively restrained styling give it a more formal character than many sports-oriented radio-controlled models.
