Automatic Pilot Chronograph Watch
IW388103 Green Dial 41mm Pilot-Style Automatic Chronograph Watch
Green Sunburst Dial · Triple Chronograph Layout · Day/Date Display · Brown Calfskin Strap
Product Overview
The IW388103 is a 41mm automatic mechanical pilot-style chronograph featuring a rich green sunburst dial, bold white Arabic numerals, and a traditional three-register chronograph layout. The combination delivers the highly legible, instrument-inspired appearance associated with classic aviation watches while adding a distinctive modern color treatment.
Three chronograph subdials organize the timing functions across the dial, while a practical day-and-date display positioned at 3 o’clock adds everyday calendar functionality. Large Arabic numerals and clear contrasting markings make the dial easy to read at a glance and reinforce its functional pilot-watch character.
The stainless-steel case combines brushed surfaces with polished accents, balancing a rugged tool-watch appearance with more refined finishing. A brown calfskin-style strap with contrasting white stitching gives this Replica chronograph a warmer, vintage-inspired look that pairs naturally with the green dial.
CORE DESIGN
Classic Pilot Chronograph with Green Sunburst Styling
The core design combines oversized white Arabic numerals, a green sunburst dial, three chronograph registers, and a day/date display at 3 o’clock. A brushed-and-polished steel case and brown leather strap complete the traditional aviation-inspired appearance.
Design Highlights
A radial sunburst finish creates changing shades of green under different lighting conditions, giving the dial greater depth without reducing its instrument-style character.
Bold white Arabic numerals provide strong contrast against the green background and preserve the highly legible appearance associated with traditional pilot watches.
Three subdials organize the mechanical timing displays while maintaining a balanced and technical cockpit-instrument-inspired appearance.
A dual calendar display at 3 o’clock shows both the weekday and date, adding practical everyday functionality to the chronograph layout.

Movement and Chronograph Functions
The watch is equipped with an automatic mechanical chronograph movement described as using a 69385-style architecture. Normal wrist movement drives the automatic winding system, helping the movement store energy during everyday wear without requiring a battery.
The chronograph system provides mechanical elapsed-time measurement through the central timing hand and three subdials. The side pushers are used to control the start, stop, and reset operations, while the main dial continues to display standard time.
A day-and-date display positioned at 3 o’clock adds useful calendar information for daily wear. The combination of chronograph counters and calendar windows gives the watch a functional, cockpit-instrument-inspired layout without losing the strong readability of the large Arabic numerals.
Classic Pilot-Watch Wearing Experience
The 41mm case provides a noticeable contemporary wrist presence while remaining versatile enough for everyday use. Its large dial opening and bold numerals make the watch appear substantial without depending on excessive decoration.
The combination of green dial and brown leather strap gives the watch a slightly vintage aviation character. It pairs naturally with denim, leather jackets, knitwear, business-casual clothing, and relaxed weekend outfits.
Wearing and Maintenance
