Product Overview
The IW500107 is a 42.3mm automatic mechanical dress watch featuring a classic silver-white dial, distinctive blue Arabic numerals, and elegant blued leaf-shaped hands. Its balanced dial layout combines traditional dress-watch styling with practical mechanical displays.
A power-reserve indicator is positioned at 3 o’clock, while a date window sits at 6 o’clock and a small-seconds subdial appears at 9 o’clock. This asymmetric three-display arrangement gives the watch its recognizable long-power-reserve aesthetic while maintaining excellent visual balance.
The polished stainless-steel round case is paired with a deep blue alligator-style leather strap. With an approximate overall weight of 111.44g, the watch offers a substantial yet refined wrist presence suited to business, formal, and smart-casual wear.
CORE DESIGN
Classic Silver-and-Blue Long Power Reserve Styling
The design combines a silver-white dial, blue Arabic numerals, blued leaf-shaped hands, a 3 o’clock power-reserve indicator, 9 o’clock small seconds, and a 6 o’clock date display. A polished steel case and blue leather strap complete the refined dress-watch appearance.
Design Highlights
The light dial creates an open and elegant background that clearly highlights the blue numerals, hands, and mechanical displays.
A dedicated indicator allows the remaining stored mechanical energy to be monitored directly from the dial.
The separate seconds display balances the power-reserve indicator and gives the dial its characteristic asymmetric layout.
The deep blue alligator-style strap coordinates naturally with the blue dial details and reinforces the formal character of the watch.

Movement and Wearing Experience
The watch is equipped with a 51011-style automatic mechanical movement. Normal wrist movement operates the automatic winding system, helping the movement store mechanical energy during everyday wear without requiring a battery.
The dial places the power-reserve display at 3 o’clock and small seconds at 9 o’clock, with the date positioned at 6 o’clock. This layout creates a distinctive visual balance and allows several practical functions to remain easy to read.
At approximately 111.44g, the watch has a solid wrist presence without the heavier feel of a full metal bracelet model. The silver-white dial and blue leather strap make it particularly suitable for suits, business clothing, formal events, and refined smart-casual outfits.
