No the key is continue to watch videos while wearing the Santos to reaffirm your purchase 😂 Lovely piece

Don't buy a watch because the "value holds up" it's all completely artificial anyway. Buy it because you love to wear it. Personally I don't like the large Santos with the date, but the medium green is my next purchase.
