The Arnold & Son Longitude Titanium is a 42.5 mm automatic titanium watch with a vertically arranged power-reserve display and small seconds. Its standard reference, 1LTAT.F01A.N001U, is specified with 100 m water resistance, COSC certification and a 60-hour reserve. The limited 5°W edition keeps the A&S6302 calibre but adds a red-gold bezel ring, a grey dial and a different included strap. This is a specification-led guide, not a hands-on review: no wrist testing or independent timing measurements are available here.
What is the Arnold & Son Longitude Titanium?
Longitude Titanium is a self-winding watch whose design combines a titanium case and integrated bracelet with a dial layout inspired, in Arnold & Son’s telling, by John Arnold’s marine chronometers. The brand describes the collection as a tribute to his role in calculating longitude at sea; that historical framing is the manufacturer’s, rather than an independently assessed claim here.
The dial places the power-reserve display at 12 o’clock and small seconds at 6, with centered hour and minute hands. Arnold & Son calls the seconds display an “imposing seconds counter” and says the arrangement pays tribute to John Arnold’s marine chronometers. The crown is screw-down, and the brand specifies 100 m water resistance.
What are the standard model’s specifications?
GPHG identifies the standard titanium model as reference 1LTAT.F01A.N001U and dates its launch to March 2024. The dimensions, water resistance and reserve below are listed by GPHG; the movement details are from Arnold & Son’s collection page.

What are the nautical design details?
Arnold & Son describes the bezel base as having 60 notches, the case band as evoking a waterline and the caseback shape as a keel. These are design references, not functional navigation features. The screw-down crown and stated 100 m water resistance are the practical specifications associated with water use; they do not establish suitability for every aquatic activity.

What to verify before buying
- Confirm whether the offer is for the standard reference or the 38-piece 5°W, and check the reference number on the paperwork.
- Ask the seller to state the current price, applicable taxes, availability and what straps are included for that specific reference.
- If seeking a replacement strap, verify the bracelet or strap interface and compatibility with the manufacturer or an authorized retailer; no exact replacement-strap reference is established here.
- Treat the published COSC status as certification information, not a guarantee of an individual watch’s present-day rate or condition.
