Thunderbirds men's watch chronograph leather strap 42 mm

Black dial, black case, black leather strap: this Thunderbirds chronograph is the kind of watch that sits quietly with a dark suit, a navy jumper or a plain white shirt. It is a 42 mm round men's watch in stainless steel, driven by a Miyota OS20 quartz movement.

Reading the dial

The dark background keeps the dial easy to read at a glance. Seconds run in a small separate sub-dial, the date sits in its own window, and a 24-hour indication helps you tell day from night. The chronograph is operated with the two pushers, and its minute counter runs up to 60. The tachymeter scale on the bezel turns a timed kilometre into an average speed: read where the seconds hand lands to get km/h. The rotating bezel doubles as a simple timer, so line its marker up with the minute hand and check the elapsed time later.

Case, glass and water resistance

The stainless steel case measures 42 mm across and 13 mm thick, so it has some presence on the wrist. Steel resists corrosion, and the mineral glass stands up to scratches better than plastic would. Water resistance is 5 ATM, which covers rain and splashes but not swimming. If you are unsure about fit, the watch size guide will help you judge how 42 mm sits on your wrist.

Movement and care

The Miyota OS20 quartz movement keeps accurate time without any servicing. When the battery eventually weakens, have it replaced by a watchmaker, who can also check the seals while the case is open.

On the wrist

The black leather strap softens and moulds to your wrist over the first weeks. Keep it away from water so it lasts. The strap is 22 mm wide between the lugs, which is the measurement to note if you ever want to swap it. With its motorsport-inspired look, it works as comfortably with weekend jeans as with office tailoring, and it arrives in a presentation box, which makes it a tidy gift.
