Invicta Men's 5139 Slim Collection Round Black Leather Watch

Thin is in with this stainless steel men's watch from Invicta's Slim Collection, which is a great choice for everyday casual wear. But with its amazingly svelte 5mm (0.2 inches) profile, it can also be perfectly tucked under the cuff when dress or business wear is called for. Offering Invicta's refined, modern styling, this watch is powered by a precisely timed Swiss-manufactured quartz movement.

And while it might be stereotypical, the truth is many of the world's finest and most accurate timing movements are created in Switzerland. This is due to the wealth of knowledge and infrastructure that's been built up in the Swiss watch industry over the centuries, and with many of the Swiss practitioners having the trade and watchmaking traditions passed down over the generations.

Matched with a supple black leather strap, this watch has an oval, gun metal gray stainless steel watch case that measures 39mm wide (1.54 inches). Its gray dial face features a two-handed movement placed in a slightly recessed center, which is surrounded by a silver tone markers and Arabic numerals. It's water resistant to 30 meters (99 feet), also known as 3 ATM. This means that it can withstand rain and splashes of water--such as car washing and showering--but it shouldn't be worn swimming.

Other features include a scratch-resistant mineral crystal, stainless steel buckle, and Tritnite luminous hands. Tritnite is a luminous material with an extended glow exclusively developed by Invicta in Switzerland and added to their timepiece hands and markers. When exposed to regular daylight, it will hold its glow for about 20 hours.

Quartz Movement
The "movement" of a watch refers to the mechanics that power the ticking of the timepiece, and this watch is powered by a Swiss-made quartz movement. It utilizes the vibrations of a tiny quartz crystal to maintain timing, which provides a fast, steady oscillation (at more than 30,000 times per second) to provide excellent accuracy.
