Price guide methods

In Ehrhardt’s Waltham Pocket Watch Identification and Price Guide (Heart of America Press, 1976), “Movements are valued as if they were in a case but you must add the value of the case for the total value of your watch.” (p. 11)

In Shugart’s Complete Price Guide to Watches (Cooksey Shugart publications, 2002), watches are priced as “having an original 14k gold-filled case.” (p. 96)

What reasoning can be brought to bear on the question of which method is best? (The interesting issue here is not about the price guides, it’s about the reasoning involved in thinking about valuation.)
