Neither of those is the new DG3804 movement. They are both the "old" ETA movements that have been around for several years now.
First link is a 2824 CHS, with fake deco engravings of 3186. Old ETA CHS movements are prone to easy breaking and should be avoided.
Second link is a 2836 ICHS without any fake engravings on it. These are solid reliable movements. The only drawback is the GMT hand is on the bottom, unlike the gen, hence the descriptor InCorrect Hand Stack (ICHS).
Trusty has taken down all the DG3804 GMTs that are the subject of this thread. It was thought he did this because of a bad batch of movements. Other dealers still list them.
Note that TSWATCH is not a TD. Send the link below to an RWI TD. Note that is says it is a DG2813. In fact it is a DG2813 variant, a DG3804. These are a lot less expensive movements than ETAs, which accounts for the lower prices. Generally speaking, DG2813 and DG3804 movements are pretty reliable but not on par with ETAs (not including the 2824 CHS mentioned above which is a modified clone ETA, and prone to easy breakage).
However, these new DG3804 CHS movements are new, have no track record, and have a known (or purported) bad batch already. Spend your money and take your chances as the carnival hawker enticed the crowds!
