Men's Double-sided Skeleton Automatic Watch Stainless Steel Case 40mm Dial Water Resistant 30M Luminous Business Tourbillon Style Brown Black Leather or Steel Band Choice
Double-sided Skeleton Automatic Watch with Luminous Dial and 40mm Steel Case

This automatic watch offers a clear view of its internal mechanics through a double-sided skeleton design. The 40mm dial diameter provides a readable face while the luminous hands and markers allow time-checking in lower light. Built with a solid steel case and your choice of steel or leather strap, this timepiece is suited to business or everyday professional use. The tourbillon movement adds visual interest to the open-worked face.
Features and Construction

The watch is constructed around a 40mm round steel case with a mineral crystal or similar face protection. The movement model 520 drives the automatic mechanism without a battery.
Material and Build
The case, buckle, and strap options are all stainless steel. The leather strap versions use genuine leather in brown or black. The steel bracelet offers a uniform metallic look while the leather options provide a contrasting texture.
Size and Practical Fit
With a 40mm dial diameter, this watch fits a range of wrist sizes comfortably. The case thickness and lug width are standard for a business-style automatic timepiece. Water resistance to 30 metres means it handles handwashing and rain but not swimming.
Uses and Placement

This watch is designed for daily wear in professional and social settings where a visible mechanical movement adds character to the outfit.
Business and Office Wear
The steel case and clean lines suit a shirt cuff or suit sleeve. The luminous dial aids time reading during evening meetings or dimly lit environments.
Everyday Casual Use
Paired with a leather strap, the watch works as a smart-casual accessory. The steel bracelet option maintains a more formal edge.
Benefits and Buying Value

An automatic watch eliminates the need for battery changes. The skeleton viewing windows offer ongoing visual appreciation of the gear train and balance wheel.
Low Maintenance Operation
The automatic movement winds through natural wrist motion. No manual winding or battery replacement is required under normal daily wear.
Why Choose This Product
This watch provides a visible tourbillon movement, luminous features, and a choice of strap materials within a single steel-cased design. It matches the description of a reliable business-style automatic watch.
