Automatic Mechanical Watch for Men with 40.5mm Case and Genuine Leather Strap

This automatic mechanical watch is a men's wristwatch with a 40.5mm case diameter and 13mm case thickness. It uses a genuine leather strap and a stainless steel buckle, and it comes in five colour combinations: brown leather with rose shell white surface, brown leather with rose shell black surface, brown leather with rose shell blue surface, black leather with black surface, and black leather with white surface. The stated chain width is 20mm and the chain circumference is 23.5cm. The product is supplied as one watch. No water resistance rating, movement calibre, or warranty period is given in the source data, so those details are not claimed here.

Features and Construction

The construction details centre on the automatic mechanical movement, the case size, the genuine leather strap, and the stainless steel buckle. These are the concrete specifications available, so the description stays within them.

Material and Build

The strap is made from genuine leather, and the buckle is made from stainless steel. These two materials form the main contact points between the watch and the wearer. The case measures 40.5mm in diameter and 13mm in thickness, giving a clear indication of the watch head size. The chain width is 20mm, which describes the strap width at the fitting point. The source does not state the case material, glass type, or movement origin, so those are left unspecified.

Size and Practical Fit

The chain circumference is 23.5cm, which is the stated strap length around the wrist. Together with the 20mm chain width, this gives a practical reference for fit. The 40.5mm case diameter and 13mm case thickness are the main watch head measurements. Because only these figures are provided, buyers should compare them with a watch they already wear if they want a close match. No adjustable range or extra strap lengths are listed.

Uses and Placement

The watch is listed for male wearers and described as business style, with student and leisure use also indicated in the title. It can therefore be considered for work, study, and everyday casual settings within those stated uses.

Event or Professional Use

With a business style and a genuine leather strap, this watch can suit office wear, meetings, and similar professional settings. The five colour options allow a choice between brown leather with rose shell white, black, or blue surface, and black leather with white or black surface. The stainless steel buckle provides the fastening method. The source does not specify a dress code level, so it should be treated as a general business-style watch.

Everyday Home Use

For daily wear at home, studying, or leisure, the automatic mechanical movement means the watch is powered by movement rather than a battery, as stated by the product type. The genuine leather strap and stainless steel buckle are the stated materials. The 23.5cm chain circumference and 20mm chain width are the fit references. No care kit or spare strap is included, and the package contains only the watch.

Benefits and Buying Value

The main buying value lies in the automatic mechanical movement, the stated materials, and the range of colour choices. These are practical, source-supported points rather than claims about performance.

Reuse and Low Maintenance

As an automatic mechanical watch, it does not require a battery, based on the movement type given. The genuine leather strap and stainless steel buckle are the only stated materials, so keeping the leather dry and storing the watch in a dry place are sensible, low-risk habits. The source does not provide a service interval, water resistance, or cleaning instructions, so no such guidance is given here.

Why Choose This Product

This watch may suit buyers who want a men's automatic mechanical watch with a 40.5mm case, a 13mm case thickness, a genuine leather strap, and a stainless steel buckle. The 20mm chain width and 23.5cm chain circumference give specific fit figures. Five colour combinations are available, covering brown and black leather with white, black, or blue surfaces. The package contains one watch, and no other accessories are listed.
