Step 1: Print a Flexible Measuring Tape

• Get a flexible measuring tape or a strip of paper.

Step 2: Wrap Around Your Wrist & Measure

• Wrap the measuring tape or paper strip around your wrist where you'd normally wear your watch.

Step 3: Check for Comfort

• Ensure that the strap is snug but not too tight. You should be able to fit one finger comfortably between your wrist and the tape or strip.

Step 4: Measuring Lug Width (a)

• Measure the space between the lugs on your watch where the strap is attached. It's usually measured in millimeters.

Step 5: Measure Buckle Width (b)

• Measure the width of the buckle where the strap connects. This measurement indicates the buckle width.

Step 6: Strap Length

• Lay the old watch strap flat and measure it from one end to the other, excluding the buckle. You'll get the total length of the strap (d).
• Additionally, measure the short side separately (c).
