What about manual kitchen scales?
Balance scales requires you to move weighted objects along a beam until they reach the same weight as the object being weighed, and the two sides balance. Not only is this process time-consuming, balance scales have several moving parts and are thus harder to clean than digital scales. Still, these scales look elegant on the countertop, so if aesthetics are more important to you, you might consider a balance scale. You can find antique replicas online, or try eBay for an actual antique.
Mechanical scales are built by placing a platform over a spring. Over time, such springs become less and less accurate. Spring scales are often cheaply made and lightweight. While they are usually inexpensive, they are often inaccurate, particularly with small quantities of light ingredients. Bread bakers should steer clear of mechanical scales. As baking expert Maggie Glezer writes, "Spring scales are either finely calibrated with small capacities or coarsely calibrated with large capacities, neither of which is very useful for bread baking."
