There are pros and cons. If you know you like larger watches or certain types, you'll be better off setting the subscription money aside and cruising ebay. You'll find stuff like this https://www.ebay.com/itm/Orient-Vintage-Diver-Automatic-Mechanical-Watch-30mt-Waterproof-Super-Luminous/154053743378?hash=item23de519312:g:VdYAAOSwoZBf2dqx
for less than the bottom tier watch gang sub and there are a good number of NOS watches you don't see everyday. If you want a surprise like the watch gang sub, pick two and have someone else hit the buy button on one!
One word of advice, if you're just starting a collection, resist the urge to buy too many inexpensive watches in a short time. NOTHING in the inexpensive world will be completely gone 6 months later.
Either way, Have fun!
