An American Watch Company

Lonegrade Luxury Timepieces

Lonegrade is setting a new standard for an American watch company by embracing longevity and rejecting the idea of having to update your wrist every season. Equal parts timeless minimalism and modern American styling, the Lonegrade Collection is designed to endure both time and trend. American watches, redefined.


Quartz vs Mechanical


Quartz movements use a microchip to convert vibrations from a small piece of quartz into impulses, which then drive a battery-powered electric motor and the watch hands. In general, these movements keep very accurate time while being affordable to make.

Mechanical movements use the energy from a wound spring instead of a battery, and keep time by regulating the release of the stored energy using a set of gears. There are two types of mechanical movements - manual and automatic.

  • Manual movements are a type of mechanical movement where the user winds the watch (typically by rotating the crown) to store energy in the spring. A full wind typically lasts around 30 - 40 hours.

  • Automatic movements self-wind by a wrists motion during wear.

Lonegrade chose Swiss Ronda Caliber 713 quartz movements for the HDR140 so we could build our watch with luxury features and lasting components here in the USA at an affordable price for consumers. Unlike many quartz movements on the market, this Swiss-made Ronda Caliber 713 is built with the highest quality standards and features 5 jewels, NIHS 91-01 shock resistance, 18.8 Oe magnetic resistance and a 3 year battery life.

The HDR140

The HDR140 is our take on an everyday watch that blends the best of classic design elements and modern minimalism.

Premium materials, lasting construction and timeless aesthetics means the HDR140 is a watch that will look as good in 25 years as it does today.

On Wrist Feel

The Lonegrade HDR140 was meticulously designed for everyday comfort.

The conservative 9mm case thickness is made to feel more slim through clever case and caseback bevels. Strategically angled and shaped lugs allow the watch to sit comfortably on the wrist of various sizes. It weighs in at 50 grams, the same as 9 quarters, and feels substantial without being restrictive.

American Made Strap

Our full grain leather watch straps are hand made in the United States.

Each HDR140 comes with full grain leather watch strap thats had dyed, cut and sewn in the United States. Sized at 4.7in x 3.15in (120mm x 80mm), it fits wrists between approximately 6.5” and 7.5“ and arrives with a 316L stainless steel buckle engraved with the Lonegrade logo.
