If you are comparing a Cronos Explorer-style watch in 36mm or 39mm, start with the exact model number. The current L6019, L6032 and L6031 listings differ in movement and dimensions, even though they belong to the same everyday-watch shortlist.
Quick choice: compare the 36mm L6019 if you want an NH35 automatic; the 36mm L6032 if you prefer the current PT5004 configuration; or the 39mm L6031 if you want a larger case with PT5000. For wrist fit, the biggest measurable difference is the move from 43.4mm to 47.5mm lug-to-lug.

Cronos L6019 vs L6032 vs L6031: Current Specifications
| Model | Case diameter | Lug-to-lug | Listed thickness | Current movement | Best starting point if... |
|---|---|---|---|---|---|
| L6019 | 36mm | 43.4mm | 11.55mm | NH35 automatic | You want a compact case and specifically prefer NH35. |
| L6032 | 36mm | 43.4mm | 10.85mm | PT5004 automatic | You want the compact format with the current PT5004 configuration. |
| L6031 | 39mm | 47.5mm | 10.75mm | PT5000 automatic | You prefer a broader case and longer footprint. |
All three current listings specify a stainless-steel case and bracelet, flat sapphire crystal with clear anti-reflective coating, BGW9 blue lume, a screw-down crown and 100m water resistance. The thickness figures above are reproduced as listed: the pages do not consistently state whether crystal height is included, so they should not be treated as measurements taken under one shared method.
36mm vs 39mm: Compare the Full Case Span
The L6019 and L6032 both measure 36mm across the case, excluding the crown, and 43.4mm from lug to lug. The L6031 is 39mm across and 47.5mm lug-to-lug. Moving to the L6031 therefore adds 3mm in diameter and 4.1mm in case span.
That longer span matters when you compare the watches with one you already wear comfortably. A 39mm case can look balanced on one wrist and extend too far across another. Bracelet end-link shape, adjustment and wrist shape also affect fit; diameter or wrist circumference alone cannot guarantee comfort.
If your current watch already reaches the edges of your wrist, use the two 36mm models as the starting point. If you prefer more dial presence and know that a 47.5mm case span works for you, shortlist the L6031. All three list a 20mm lug width, but matching width alone does not establish compatibility with a fitted bracelet or end link.
L6019 vs L6032: Same Listed Footprint, Different Movement
The L6019 uses NH35, while the current L6032 uses PT5004. Both share the same stated diameter and lug-to-lug length. This makes them the closer comparison when you have already decided on a compact 36mm case.
Choose the L6019 if NH35 is part of your buying preference. Our NH35 movement guide covers its operation and ownership considerations. Choose the L6032 if you specifically want the current PT5004 option; the PT5004 movement guide explains the current no-date implementations and the limits of the available specifications.
The L6032 has a lower listed thickness number, but the measurement caveat above still applies. Movement name and listed thickness alone do not establish better accuracy, reliability or comfort. Check the current dial choices and the complete watch before deciding.
Where the 39mm L6031 Fits
The L6031 combines its 39mm case and 47.5mm lug-to-lug length with a PT5000 automatic movement. Its current listing offers enamel black and blue dial options and lists a 10.75mm thickness.
It is the clearest choice in this group when a larger case is your priority. Do not treat it as simply an enlarged L6032: the current movement names differ, and the extra case span changes the sizing comparison. If your main concern is fit, settle the 36mm-versus-39mm question before comparing the movements.
Why You May See Different Movement Names
Older listings, review titles or links between products may use different movement wording. For this comparison, the current L6032 specification and selectable variants identify PT5004; the current L6031 specification and variants identify PT5000. The L6019 identifies NH35.
Use the current specification and selected variant together. A movement named in an old title or a related-product link is not enough to identify the watch you will receive. If those details disagree on a listing you are considering, ask for confirmation before ordering.
Frequently Asked Questions
Which current Cronos Explorer-style models are 36mm?
The L6019 and L6032 compared here both specify a 36mm case and 43.4mm lug-to-lug length. Their current movements are NH35 and PT5004 respectively.
Which one is 39mm?
The L6031 specifies a 39mm case, 47.5mm lug-to-lug length and PT5000 automatic movement.
Is L6032 currently PT5000 or PT5004?
The Watchdives L6032 listing checked for this guide specifies PT5004 in both the product specification and selectable variants. Check the linked current product page when ordering.
Which should I consider for a smaller wrist?
Start by comparing the 43.4mm lug-to-lug L6019 and L6032 with a watch that already fits you. They have a shorter stated case span than L6031, but bracelet fit and your preferred proportions still matter.
Does the 100m rating make these certified dive watches?
The listings state 100m water resistance. That figure alone does not establish dive certification or suitability for every water activity; follow the guidance for the exact watch and its condition.
Compare Current Options
Use L6019 for 36mm with NH35, L6032 for 36mm with PT5004, and L6031 for 39mm with PT5000 as your shortlist. Each had at least one available variant when checked; colors and availability can change independently.
