For a traditional formal look, choose a slim black or brown leather strap. Black is the more restrained, classic option; brown adds warmth against a white dial. Before ordering, verify the watch’s lug width and shape, then check buckle compatibility and strap length. A white strap is another possible look, but it is a personal style choice rather than the traditional formal default.

Black leather for a restrained, traditional pairing
NOMOS Glashütte describes the traditional formal dress-watch choice as “a slim leather strap in black or brown.” Black is the quieter of those pairings and suits a deliberately understated look. NOMOS Glashütte’s strap guidance

Brown leather for warmth
Brown is a dress-appropriate alternative when you want less visual severity than black. Timex’s white-watch collection describes brown leather as a particularly warm, dressier look against a white face. The effect will vary with the particular shade and finish, so consider the strap alongside the dial and case rather than treating every brown strap as interchangeable. Timex’s white-watch collection

White leather as a personal style choice
White straps are available, including examples listed by Jaeger-LeCoultre and Barton. Their availability does not establish white-on-white as the best formal match; choose it if you prefer a coordinated, more conspicuous look, not because it is the traditional default.

Verify fit before buying
The distance between the watch’s lugs determines its lug width. Measure that gap or use the manufacturer’s specifications for your exact watch reference; do not assume a universal or “standard” size. Barton lists strap widths from 16 mm through 24 mm, illustrating how much sizes can differ. Browse a leather watch strap in your lug width only after confirming the measurement and fit.
Check more than the lug width
Confirm that the strap fits the lug shape and that its buckle end works with your buckle. Check the strap’s length against your wrist, too. Specifications can be model-specific: Jaeger-LeCoultre lists its white alligator strap QC2196BI with a 19 mm lug width, a straight lug with Squadra insert, compatibility with a 16 mm buckle, and separate strand lengths of 65 mm at 12 o’clock and 105 mm at 6 o’clock. These figures describe that strap, not a general sizing rule. The listing also says the buckle is not included. Jaeger-LeCoultre QC2196BI specifications

Standard spring bars
For a watch without quick release, follow the watchmaker’s strap-change instructions. If those instructions call for it, use an appropriately compatible spring-bar tool; the cited makers do not prescribe a particular tool model. Jaeger-LeCoultre also recommends its boutique or an authorized dealer as an alternative for its strap changes. Barton’s quick-release information
