36mm × approximately 43mm L2L stainless steel three-piece Oyster — case middle, threaded caseback, threaded crown. Watch-Wiki's Air-King history reads the case smaller, describing the 5504 as a "larger 35 mm Air-King for export markets" rather than 36mm; one specialist-dealer listing gives the same 35mm figure. The 1016 Explorer case-architecture match and the documented 19mm-lug bracelet fitments support the 36mm reading, so this article treats 36mm as the primary figure and flags the 35mm reading as a documented disagreement. The case envelope is shared with the 1016 Explorer and the preceding 6610 Explorer; the 5504's distinctness from those references is dial-side and movement-side rather than case-side. Lug width is 19mm, consistent with the 1016 Explorer / 5500 / 6610 architecture and with the documented period-correct bracelet fitments (7205, 7206, later 78360). Some sources read the 5504's lugs as 20mm — Robb Report and one specialist-dealer listing both note 20mm — but the bracelet-evidence (7206 rivet with 58 end-links is a 19mm fitment, documented on Eric Wind's documented 5504) reads firmly at 19mm. The 20mm reading is an editorial error. | 36mm × approximately 43mm L2L stainless steel three-piece Oyster — case middle, threaded caseback, threaded crown.
