On Holden’s list, Probably Want At Some Point
Longines Conquest Heritage Central Power Reserve
The Longines Conquest Heritage Central Power Reserve (L1.648.4.78.2) is a complication watch from Longines: a 38 mm stainless steel case, 12.3 mm thick, with an automatic L896.5 movement and 50 m water resistance.
Its lug-to-lug length is unknown, so wrist fit can only be judged from the 38 mm case width.
Research found it at $3,800 list in the US (checked August 2026).

Will it fit?
The research didn’t find a sourced lug-to-lug length for this watch, so the fit can’t be estimated here. If you can measure one, try it in the wrist-fit tool.
What the research found
These are the research’s judgments, scored against Holden’s priorities, not his own words.
Strengths
- A complication display effectively unique in the industry — central twin-disc power reserve reviving Longines' own 1959 ref. 9028 [2][4]
- Box sapphire, domed three-part dial, faceted appliques, decorated movement — high execution density [3]
- Silicon + 72 h in a heritage package [3]
Weaknesses
- 12.3 mm is tall for a 38 mm dressish watch (box crystal explains part of it)
- Proprietary disc module means factory-only service for the signature feature
- 19 mm lug width — awkward strap size
