SQ30 Eclipse Solar Black-Ion [42mm]

$288.00
Inspired by watches like the iconic Chronosport UDT and Sea Quartz 30, the SQ30 Eclipse Black-Ion blends classic military style with new solar technology. In serious situations, standing out can be deadly. That is why special forces loved the low-key black case of the original UDT watch. Other traits of the Chronosport UDT also remain — it's legible, reliable, low-maintenance, and most importantly, still affordable. The fact that solar movements are also better for the environment, result in fewer batteries ending up in landfills, have longer service intervals, and come standard with a 6-year warranty is not so bad either.

Inspired by Icons

Before starting Momentum, our founder and president, Simon, owned a company called Chronosport. The original 1980s Chronosport UDT was famously worn by many special-operations military groups around the world, along with celebrities like Sylvester Stallone in Rambo III. The original Sea Quartz 30 was also famously worn by Tom Selleck in Magnum PI.

Solar-Powered Movement

We believe in sustainability through durability. Solar-powered watches require less servicing and result in less batteries used over the product's lifespan. With solar watches, we also provide a 6-year warranty out the box, no 2-year service intervals required. The solar movement charges in any light, allowing the Eclipse to run for up to 6 months in pitch darkness.

A crackin’ watch

This is my daily go to watch. Tactial, robust, accurate, fun and has charm. The Seiko day/date window is an extra bonus.

Fantastic piece. Fits nicely on a small wrist (6.7 inch) and not too heavy or lightweight. Extremely easy to read, looks better in person than photos and lume is solid. Links on the bracelet are a bit more stiff to change and adjust but nothing too unmanageable. Worth the price!

gone fishin'

I have found both this and the Momentum Smoke Jumper version of their solars, to be excellent watches for my extended trips to the bush in Alaska. Light and never have to set the time. Bullet proof and maintains accuracy...for a long time! Use the SQ as the primary and pack the Smoke Jumper as a back up….plus it looks good!

SQ30 quality issues?

Great looking watch, but I’ve experienced quality issues. First ordered didn’t work at all, sent it back and received a replacement. Second one worked fine for a week or two then started to slow down, or stop randomly - and was fully charged in the sun for 6+ hours. That one is on the way back now for repair or replacement. The customer service has been great, but I am disappointed with these issues. Hopefully watch #3 will change my mind, otherwise I’ll ask for a full refund.
