Why KTT?

Quality Over Quantity

For over 10 years we have built our business on providing friendly service, a beautiful website, in-depth information and detailed videos. We deal in watches that you usually won't find together in the same place - from Rolex to Invicta and modern microbrands to antique pocket watches. Check back often, you never know what you will find!

Why Ktt Specs

Watch You See Is Watch You Get

Since the beginning, KeepTheTime has refused to use stock photos. After passing through our logging and inspection process, our in-house photographer gets up close and personal with each watch. After the photoshoot, we begin our research, verifying the detailed specs by hand. That's why you will know exactly what you are getting when buy from us.

Why Ktt Photos

Ready to Wear

Some watch dealers don't bother to clean the used watches they sell... you can see the dirt and grime in their pics, gross! At KTT, we're unabashed germophobes. That's why we thoroughly sanitize every watch before we even begin posting it, then once again before shipping. Your watch will arrive clean and ready to wear!

Why Ktt Clean

Second To None Packing + Shipping

One of our favorite customer comments is that KeepTheTime is the Brinks Truck of shipping watches. We take packing very seriously, from the use of biodegradable peanuts (pet friendly!) to absurd amounts of packing tape, you can rest assured that your new-to-you watch will arrive safely. Some of our competitors ship within 1-2 weeks because they take your money first then try to source the watch second. KeepTheTime watches are in stock and ready to ship. That means we can get your order on its way within hours not days.

Why Ktt Packing

Our Other Project

Spreading movement awareness. When we’re not filming, reviewing and trading watches, we’re building a community for enthusiasts to geek out about what makes their timepieces tick. Caliber Corner is a movement database and forum for collectors who want to learn about watches, not just wear them. Join the movement.
