Notched Leather Strap for a Concord Chronograph
Concord's integrated-case chronographs are built so the bracelet flows straight out of the case, which means a standard strap physically cannot slot into the lug recess. The fix is a notched strap for a Concord chronograph: black Epsom, center-notched to the exact measurements of the case opening so the leather tucks in where a normal band would stand off.

Why these choices
Epsom is a stamped-grain calfskin, the same family of leather used on Hermes bags. It is light, holds its shape, and shrugs off scratches, which makes it a sensible face for a watch whose case sides sit right against the strap. In black it keeps the notched build looking factory rather than aftermarket.
The notch itself is the whole job. A center notch (X 20 mm across, Y 8 mm deep, Z 4 mm tongue) is cut to the case, and we recommend a jeweler-measured opening because a millimeter of error shows. This owner runs a deployant, and noted the strap does not need a center cut on the buckle side because the folding clasp handles closure, so we built it to feed straight into that mechanism.
If your integrated watch is a different make, the same measured approach covers Cartier, G-Shock conversions and vintage dress cases through the custom notched straps range. This one started from the center-notched strap base and was cut from there.
Integrated cases are the exact scenario a notched strap exists for: the lugs and case flow into one shape, so there is no open lug gap for a normal spring-bar strap to sit in. Cutting the notch into the leather itself lets the strap slot into that recess and sit as tight as the original bracelet did. Epsom helps here too, because its firm stamped grain keeps the notched end from stretching out of shape where it wraps hard against the case sides day after day.

“I was a bit apprehensive when I sent off my measurements, I kept thinking that I had got them totally wrong, but when the strap arrived and was fitted I was pleased to say it fitted perfectly!”

FAQ
How do you get a notched strap to fit a Concord?
You send the three notch measurements (width, depth and tongue) taken from the case opening, ideally jeweler-measured, and the strap is cut to them so it seats flush.
Center-notched or corner-notched for this watch?
This build is center-notched, where the tongue sits in the middle of the strap end. Corner-notched is the Cartier Santos pattern. The right one depends on where your case opening sits.
Notched straps are made to your measurements and built to order, so allow 2 to 3 weeks to delivery. Send photos with your numbers and we will confirm the cut before we start.
