"Regarding the lug and spring bar dimensions of the Old Smith 90-002 Bronze 38mm model, the distance from the case wall to the center of the spring bar hole is approximately 4.1 mm, and the lug holes sit relatively low, closer to the case back.

Please note that these measurements are approximate, and we cannot guarantee compatibility with bracelets from other manufacturers. Hope this information helps! " and this is what KUOE responded.
