Fit & sizing notes for the Bambino 38mm
- Width: buy 20mm straps. Tapered straps listed as 20/18mm or 20/16mm fit too; only the first number has to match. See strap sizes explained.
- Spring bars: 20mm long. We haven't confirmed the diameter for this model, so measure the old bar before buying replacements (spring bar sizes).
- Wrist fit: at 44mm lug-to-lug it should sit within the top of wrists from about 14.7cm up (rule of thumb: lug-to-lug under ~30% of wrist size). That's longer than 8% of the watches in our index. See what size watch suits your wrist.
- Strap thickness: at 12.5mm thick it's mid-thickness, so most straps suit it; padded leather and NATOs both balance well.

Orient Bambino 38mm — strap questions
What size strap does the Bambino 38mm take?
The Orient Bambino 38mm has a 20mm lug width, so you need a 20mm watch strap.
Will any 20mm strap fit the Bambino 38mm?
Most will. Width is the main thing to match, but also check that the strap's spring-bar holes suit the bars, and that the strap is thin enough to clear the case between the lugs. A metal bracelet needs 20mm end-links made for this model.
What spring bar size does the Bambino 38mm use?
20mm long. We haven't confirmed the diameter for the Bambino 38mm, so measure the original bar with calipers before buying replacements.
Is the Bambino 38mm good for strap swapping?
Yes. With standard 20mm spring-bar lugs, NATO, leather, rubber and mesh straps can all be fitted with a spring-bar tool.
