Brown dial on the blacked out case is a killer look.Customer feedback
Richer brown in person than in the photos.Customer feedback
Went with the rubber strap. Comfortable enough to forget it's on.Customer feedback
Fast shipping and it came properly boxed with the tools.Customer feedback
I got the steel strap version and it completely changes the feel. Dressier than I expected from a G shape.Customer feedback
John helped me pick between the rubber and the steel. Went steel, no regrets ☕Customer feedback
Octagonal case with a brown dial shouldn't work as well as it does. Goes with everything I own.Customer feedback
I was torn between this and a plain black one and I'm glad I went mocha. The dial has real depth to it, more of a coffee tone than a flat tan, and it works with brown leather or steel depending on which strap I throw on. Build quality is solid, arrived in about two weeks, and the presentation case was a genuinely nice touch.Customer feedback

Before You Order
Mocha Oak begins with a GA-2100. Chrono Customs gives it a dark steel case and mocha dial, with your choice of rubber strap or steel bracelet. It is an independently customized watch, not a factory edition.
The case measures 44 mm. The listed wrist range is 15–21 cm. Send John your wrist size if you would like help checking the fit before you order.
Your watch ships within five calendar days of your order. The date near the buy buttons is the dispatch date—not the arrival date. We then send it by tracked express shipping. Shipping fees and duties are covered.
No winding or daily charging. The battery-powered GA-2100 has analog hands, a digital display, world time, a stopwatch, a timer, five daily alarms and a double LED light.
This watch is rated to 200M water resistance, suitable for swimming and snorkelling. Do not press the buttons underwater. The rating is not a scuba-diving certification.
You have 30 days from delivery to request a refund. Contact John to arrange your return.
Ask John About A ReturnYour watch comes with a two-year warranty. If you need help with a repair, service or a part later on, contact John. Support continues after the warranty ends; any work outside warranty can be discussed with you.
A warm mocha-brown dial sits inside a dark steel case. Choose a brown rubber strap or a steel bracelet. The gallery shows how the finish looks from different angles.
