I’m currently working on a personal version of the Mecascape[0] (as much because of the cost as a chance to play with some hardware ideas). Taking it on travels is part of the fun.

Bought a travel click by Braun a few years bact to put next to me when I work. The quality is abysmal, the hour arm is half to a full hour ahead after I used for a while. And it costs like 30 bucks I guess one just pays for the brand name while the product is the same quality as no-name ones on aliexpress for a tenth of the price.
