The SSK019 was introduced as part of Seiko's second wave of SKX-style GMT models in late 2023. The SSK017, SSK019, and SSK021 were announced together around October 2023 as U.S. Special Creation GMT variants.
Reference: SSK019

Nickname: Batman GMT / Batgirl GMT (unofficial)
Case Size: 42.5mm

The SSK019 is somewhat unique in the lineup because it combines:

Red GMT accents

Many collectors consider it one of the most attractive GMT colorways after the Pepsi SSK003 because it feels more understated while still having the classic red/blue GMT look.
