Seiko Speedtimer vs Tissot Chrono XL

Swiss quartz with sapphire and 100m, 2mm thinner than the Seiko, on a standard 22mm strap, with an indicator that warns before the battery dies.

45mm across. It scores a fraction higher than the Seiko on our formula, mostly on the strap width; on most wrists the Seiko is the better fit.

Tissot publishes a US service price list, which almost no chronograph maker at this level does, and PowerDrive drives the hands back to zero electronically instead of through a column wheel. Cheap to keep, and 45mm across.

If you want the Speedtimer's light power and the Tissot's presence, Citizen's World Chronograph A-T adds radio-controlled time, a perpetual calendar and 200m behind sapphire, with five years of warranty.

43mm on a 23mm strap, and a module whose future depends on Citizen.

Sapphire, 200m, a perpetual calendar and a chronograph that runs on light — and a 23mm lug width, which is the least common strap size on this site. It is a module rather than a movement, so its long-term future depends on Citizen continuing to support the H800.

No battery to change, a power-reserve indicator, three years of warranty and a published $163 V-series service — and a 45.9mm lug-to-lug that fits wrists the Tissot overhangs.

The 21mm lug width costs you at strap time, and it is 2mm thicker than the Tissot.

Seiko lists V-series solar service at $163 — cheaper than a 4R36 overhaul and far cheaper than a mechanical chronograph. The 21mm lug width is the annoyance: standard straps come in 20 and 22.

A 38mm titanium mecha-quartz chronograph with sapphire, 200m and a 44mm lug-to-lug — smaller than either.

BOLDR states no warranty term. Sold direct; we earn nothing on this link.

Mecha-quartz splits the difference honestly: quartz timekeeping, a mechanical chronograph reset, and a battery any shop stocks. The VK64 is a module — when it dies it is replaced, not rebuilt.
