No. As a professional auto repair technician I understand the concept of preventive maintenance. However, There is really no comparison between the two. A watch has few friction points, and the worst case scenario if they're ignored is that a few relatively inexpensive bearings and components will require replacement. The entire mechanism isn't degraded.
The same can't be said for an auto engine. First, there are many more friction points; main & rod bearings, crankshaft journals, cam lobes, journals, and followers, valve stems and guides, piston skirts and rings, cylinder walls, etc, etc. Second, engine parts tend to be more expensive than those for watches. Third, labour rates for engine repairs are usually considerably more than for watches.
