If you want a chronograph and want to keep it, this is the answer. Seiko's published $163 solar service is less than a 4R36 overhaul and roughly half a mechanical chronograph's, and there is no battery to change.
Sapphire with inner anti-reflective coating, a tachymeter, a power-reserve indicator and six months of running on a full charge. 41.4mm, 45.9mm lug-to-lug, 13mm thick — and a 21mm lug width that will annoy you.
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.
