Although I prefer my watches on a (leather) strap, I wondered what a Dato on a bracelet would look like. I used the bracelets as shown on the Lange website used for the WG Langematik (with Date) and the ?weavy? bracelet as used on the PT Langematik Perpetual.
Results:


I am not sure, but I think the first two bracelets are available for the Lange-1 and thus will fit the Dato too. The last ?Perpetual? bracelet is, if I am not mistaken, only available for the Perpetual Langematik and is 19mm wide at the lugs and will not fit the 20mm Datograph lugs.
Best regards,
Edwin
