Best Watch Straps for the Baltic Aquascaphe
Baltic Watches was founded in Paris by Etienne Malec, who grew up around his father's collection of vintage timepieces and set out to recreate the specific character of 1950s and 1960s dive watches at an accessible price. The Aquascaphe — Baltic's second model and the one that established the brand as a serious player in the microbrand space — is a direct interpretation of the professional dive watch aesthetic of that era: entirely brushed case, oversized screw-down crown without guards, coin-edge bezel, drilled lugs, multi-layer sandwich dial with beige or gilt lume tracks, and dimensions drawn from the original professional divers rather than the inflated case sizes of modern sports watches.
The Aquascaphe ships at 39mm — the same diameter as the original Blancpain Fifty Fathoms, the Omega Seamaster 300, and the Rolex Submariner of the 1950s. At 13mm thick and 47mm lug-to-lug, it sits on the wrist as those original dive watches did. This is not coincidental. Every dimension of the Aquascaphe is a deliberate act of historical reference.
The result is one of the most strap-receptive watches in the current market. The Baltic community is among the most strap-enthusiastic of any watch brand at any price point — scroll any Baltic forum thread or Instagram hashtag and the Aquascaphe appears in more strap combinations than almost any other watch. The drilled lugs, the 20mm standard lug width, and the vintage character that rewards aged, textured materials all make the Aquascaphe a watch built for strap experimentation.
Baltic Aquascaphe Strap Size
Every Baltic Aquascaphe reference uses 20mm lugs — confirmed by Baltic's own official specifications across all variants.
Aquascaphe Classic (all colourways — Blue Gilt, Black Silver, Black Cream, SB01) — 20mm. 39mm case, 13mm thick, 47mm lug-to-lug. Drilled lugs.
Aquascaphe MK2 (Blue, Grey and all MK2 variants) — 20mm. 37mm or 39.5mm at the bezel, 12.9mm thick. Drilled lugs.
Aquascaphe Bronze (Black, Blue) — 20mm. 39mm case, 13mm thick. Bronze CuAl8 case. Drilled lugs.
Aquascaphe GMT — 20mm. 39mm case. Drilled lugs.
Order 20mm for any Aquascaphe reference without exception. The drilled lug holes make strap changing straightforward with a standard 1mm spring bar tool.
The Vintage Character — Why Certain Straps Work and Others Don't
The Aquascaphe's vintage 1950s design language creates a clear strap logic. Baltic's own factory strap choices — a tropical-pattern rubber and a beads-of-rice bracelet — are both deliberate historical references to the straps worn on professional dive watches of the Aquascaphe's design era. Every strap decision should either honour this vintage character or create a deliberate, considered contrast with it.
Straps that work well: tropical FKM rubber, warm brown leather, canvas, tan suede, aged two-stitch calfskin, perlon. These all reference the materials of the era or complement the warm beige lume and gilt detail of the dial.
Straps that contradict the character: highly polished formal leather, fine dress calfskin, thick corporate rubber. The Aquascaphe is not a dress watch and does not benefit from being dressed as one.
Best Rubber Straps for the Baltic Aquascaphe
Tropical style FKM in black at 20mm — the most historically resonant and most celebrated Aquascaphe combination. Baltic ships the Classic on a tropical-pattern rubber as standard — validating this as the factory choice. The vintage basket-weave and honeycomb surface patterns reference the Tropic-brand rubber straps of the 1950s and 1960s that professional dive watches of the Aquascaphe's era were actually worn on. On the Blue Gilt or Black Cream variants with their warm beige lume, tropical black rubber creates the most period-correct active combination available.
Brown tropical FKM at 20mm — the most specifically vintage and most discussed non-black rubber combination. The warm brown tropical rubber echoes the beige lume and gilt tracks of the Blue Gilt and Black Cream variants — warm tones referencing the aged rubber of original 1950s and 1960s dive watches. This is one of the most photographed Aquascaphe combinations in the community.
Classic FKM rubber in black at 20mm — the most practical waterproof daily choice for the Aquascaphe's 200m water resistance.
Dial and case-specific recommendations:
- Blue Gilt / Black Cream (beige lume) — brown tropical FKM for the most warm vintage palette; black tropical FKM for the most operationally coherent
- Black Silver (white lume) — black tropical FKM for the most composed vintage combination; grey FKM for a cool tonal palette
- Bronze case — brown tropical FKM — warm rubber echoing the bronze patina directly
All at 20mm.
Best Nylon Straps for the Baltic Aquascaphe
Single-pass nylon — Original at 20mm with the CNS solid buckle. The Aquascaphe's 1950s professional dive watch heritage is the same world that produced the MOD-specification single-pass strap. Most appropriate Aquascaphe colourways:
- Black — the most minimal and most operationally coherent across all dial variants.
- Navy — for the blue dial variants. Creates a cool, maritime tonal combination.
- Olive / khaki — for an expedition-adjacent, professional-equipment aesthetic.
- Black and grey — the most collector-oriented understated combination.
Marine Nationale elastic at 20mm — the most comfortable Aquascaphe daily wear option. The French Navy combat swimmer heritage of the Marine Nationale strap connects directly to the professional diving world the Aquascaphe references. Navy or black.
RAF single-pass nylon at 20mm — the RAF 6B/2617 specification was introduced in 1954 — the same era of professional diving equipment that inspired the Aquascaphe. Both the strap and the watch reference the same operational world.
Canvas at 20mm in olive or black — canvas is a particularly good choice for the Aquascaphe given the brand's Paris-based identity — French canvas manufacturing tradition alongside French watch design creates a coherent combination.
Perlon at 20mm — grey or navy perlon gives the Aquascaphe a refined, unexpected character. The slim perlon construction suits the 13mm case profile proportionally and creates the most dress-adjacent Aquascaphe combination without using leather.
Paratrooper elastic at 20mm — the most comfortable daily-wear option.
Best Leather Straps for the Baltic Aquascaphe
Leather transforms the Aquascaphe more dramatically than almost any other watch at its price point. The vintage sandwich dial and fully brushed case are receptive to warm, textured leather in a way that modern sports watches cannot match.
Brown vintage two-stitch calfskin at 20mm — the most celebrated Aquascaphe leather combination and the most discussed in the Baltic community. The warm brown and two-stitch construction reference the 1950s professional dive watch era directly — the same era of equipment the Aquascaphe's design draws from. On the Blue Gilt dial, warm brown leather against the blue dial and gilt lume creates a warm-cool contrast that is immediately compelling. On the Black Cream variant with beige lume, the warm brown creates a fully warm, unified palette.
Dark brown padded calfskin at 20mm — the most substantial everyday leather. The padded construction suits the Aquascaphe's 13mm case thickness proportionally.
Tan suede at 20mm — the most relaxed and most specifically vintage-expedition leather. Tan suede references the worn leather equipment of 1950s and 1960s expeditions and professional diving operations. Particularly effective on the Blue Gilt and Black Cream variants where the warm tan echoes the beige lume.
Classic black calfskin at 20mm — the most formal Aquascaphe combination. Effective on the Black Silver variant for a composed, monochromatic palette.
Dark brown suede at 20mm — for smart-casual contexts.
The Bronze Aquascaphe — Specific Strap Logic
The Bronze Aquascaphe develops a natural patina over time — the bronze case slowly oxidising to warm green-brown tones that cannot be predicted or replicated. This living case material creates a specific and unusually personal strap logic.
Brown tropical FKM at 20mm — the warm brown rubber echoes the bronze patina at all stages of development. As the bronze ages to darker tones, the warm brown rubber ages with it.
Brown vintage two-stitch leather at 20mm — the leather ages alongside the bronze case. Two materials that develop genuine character over time on the same watch.
Tan suede at 20mm — the warm tan against the bronze creates a warm, earthy palette that references the archaic character of bronze itself.
Recommended Combinations
Most historically resonant — black tropical FKM at 20mm — Baltic's own factory choice, 1950s era rubber on a 1950s-inspired case.

Most characterful leather — brown vintage two-stitch at 20mm — 1950s dive watch heritage in leather form.
Most relaxed vintage — tan suede at 20mm — warm expedition leather echoing the beige lume.
Most operationally coherent nylon — Marine Nationale elastic at 20mm — French Navy combat swimmer heritage on a French-designed dive watch.
Bronze case — most coherent — brown tropical FKM or brown vintage two-stitch leather — warm materials ageing alongside a warm case.
Most refined casual — grey perlon at 20mm.
Frequently Asked Questions
What size strap does the Baltic Aquascaphe take? 20mm — confirmed by Baltic's official specifications across every Aquascaphe variant including the Classic, MK2, Bronze, GMT, and SB01. The lugs are drilled through on all references, making strap changing straightforward with a standard spring bar tool.
What is the best rubber strap for the Baltic Aquascaphe? Black tropical style FKM at 20mm — Baltic ships the Aquascaphe Classic on a tropical-pattern rubber as standard, confirming this as the factory-validated choice. The vintage basket-weave pattern references the 1950s Tropic-brand rubber that professional dive watches of the Aquascaphe's design era were worn on. Brown tropical FKM for the Blue Gilt and Black Cream variants with warm beige lume.
What is the best leather strap for the Baltic Aquascaphe? Brown vintage two-stitch calfskin at 20mm — the most celebrated Aquascaphe leather combination in the community. The warm brown references the 1950s era of the watch's design inspiration and creates a compelling warm-cool contrast on the Blue Gilt variant.
Why does the Baltic community change straps so frequently? Three factors make the Aquascaphe particularly rewarding for strap experimentation: the standard 20mm drilled lugs provide easy tool-free changes; the vintage design language responds dramatically differently to each material — the same watch reads as completely different pieces on tropical rubber versus warm leather versus perlon; and the accessible price point means the cost of a quality strap represents a meaningful proportional upgrade that transforms the watch's character.
What is the difference between the Aquascaphe Classic and the MK2? The MK2, introduced in 2024, refines the Classic with sharper case angles, vertical brushing on the lug tops instead of circular finishing, an improved bezel grip, and updated movement (SB02 calibre). Both use 20mm drilled lugs and accept identical straps. The MK2 comes in 37mm and 39.5mm case sizes; the Classic is 39mm.
